Here it is. Total seperation
Let's talk about it

Ouch!
looks like bad weld penetration right there...
two pieces of metal should never break right on the weld.. if it was welded correctly....
So we can be sure that we're looking at the same thing, this is the same mount right?

They are way too big to be having stuff like this happen, and on multiple occasions no less. It's so much better to over engineer and over build from a safety and liability standpoint. Not to mention reputation.
In this case, the execution is very poor. They probably welded it and ground it clean for appearance. The initial weld didn't penetrate, and they cleaned off the only part that had any strength to it. On a structural application, I would be very reluctant to grind a weld for the sake of appearance. To me there is nothing prettier than a nice, clean, properly laid weld. That entire seam should have been welded on one side, with at least 1" welds spaced 1" apart on the other side. Personally, I'd weld it on both sides if there is room.
There is absolutely no excuse for that.
Nope, the other one.
KT
Did both sides rip loose. That is the first one of his new ones I have seem fail as a lot of the vintage racers are using them and no failures so far.
here's the bar from the website

Do you know the year yours was made?
Mine is the 'newer model', but I do keep an eye on it.
I have a couple of ideas to reinforce it. I may need to do so on mine someday.
If you send it to me, I'll fix it for you for free.
Trekkor bought this mount from me. It is the new style that Jim Patrick sold to me to cure my previous issues with the older bar.
The failure looks the same as my original failure.
Sorry Trek.....
As John says, this is the first of the new style mounts that I have heard about failing.
It's hard to believe that it would be overstressed with the torque of your 2.0/2.2 liter. Something else caused this.
Bill P.
Those quick mounts have had a history of breaking.
Gee, that looks like I welded it...
It's strange that there's even a weld there. A stronger, and cheaper, way to fabricate that part would be to have the whole part other than the bar made as one pressed piece. This would be very unlikely to break, and even if the welds to attach it to the bar broke, they'd be resting on the bar. Lots of clunking noises, but nothing would fall down.
I don't know the year. But it is a total failure.

There no penetration in that weld.
Seriously, send it to me. I'd like to give it a try.
I've been looking foward to Mikey's pleasant and dignified response to this since it happened.
Pretty sad when you are under a car and see this and the first thing that pops into your head is "Zois". ( in the Seinfeld voice, just like when he says, "Newman" )

Thanks Joe, I'll keep you in mind. really nice of you.
My buddy might just be willing to drive up with his truck mounted welding rig and fix it on site. : welder:
It has to come out of the car to be repaired properly, I can see that very clearly.
KT
My laptop screen isn't the best, but it looks like it was welded on the inside. A nice filet weld around there should be super strong, someone just had no idea what they were doing. That's one of the dangerous things about Mig, it can look ok, and have no strength to it. When you are welding, it's plain as day when you get good penetration if you know what to look for. I don't think it needs to be beefed up so much as done properly.
on edit: I'd like to see them use a little thicker plate too, if we're being picky.
I just emailed pictures to Jim.
We'll see what happens.
Besides just welding, it should be stress relieved in an oven.
I have access to an oven that could do the job.
Trekkor,
This failure is much worse than mine was. I still had weld contact on the bar. Your's is a complete failure.
Glad to hear you are thinking of taking it out. You won't be able to do it right in the car. Pull the motor and clean it up.
Bummer dude....
Bill P.
Duct TAPE!
Sucks Trekkor. I'm sure the fixed version will work fine.
You need a smaller motor. Build a nice 1600 cc six cylinder.
Wow Andy, that's a pretty vivid description... I take it it's a first hand experience?

That would have been "a problem".
"Alameda, we have a problem".
I'm thinking about working on it NOW, as it is just hanging there on the trailer.

Where are the welds? Looks like they forgot to weld it up. I just fixed a goof I made on my tubing bender that only involved 4 inches of weld and it was a major PITA to get those 2 pieces of steel separated. Lots of grinding and pounding with a BFH
I read the posts through several times and am still confused? Is this the early mount that uses the 4 cylinder mount ears or the later one that bolts to the bulkhead? The early design was flawed due to the long/bent tubes that allow the engine to twist and move and it is worse on a track car since the rear part of the car where the tranny is bolted is moving too. If it was the early one, I'd get rid of it.
As a side note, when the shop put the six in my race car, we used an empty 2L block and tranny to test fit things. When doing this the trand mounts were found to be off about 5/16 inch to one side and were modified so the engine was bolted in with no stress on the mounts, front and rear. You might want to consider checking that when things get calmed down and you have some time?
Dude! I can not believe they let that mount out of the shop
like that. Your really lucky that nothing worse happened, you must
have been four leaf clovers when that happened.
That's just wrong...
John,
Trekkor bought the mount in his car from me. It is the 2nd generation crossbar mount that supposedly addressed the cracking issue of the Gen I crossbar mounts. I had rewelded the old Gen I mount and was still running it in our old 914-6 when I sold it. Jim Patrick had given me a discount on the Gen II crossbar mount because he did not like the welding being done on the Gen I mount as per Demick's explaination.
I also bought the PMS bulkhead mount and would have sold that to Trekkor when I bought The Beast (which has the RJ mount already), but I had sold the bulkhead mount and I had not found any mention of failures with the Gen II mounts.
I'm just blown away that the whole mount came undone.
Bill P.
And how was it again, that the factory 6 engine mount was attached????
What was that, did someone say bulkhead?
I don't understand why the idea of upgrading to a bulkhead mount keeps getting brushed off either. Is there a disadvantage to it?
Guys, come on.........
I did my 6 conversion in about 98....pre internet days for me.
At the time, it was widely held that NONE of the bar type mounts
were worth a shit. I had to get a Vellious bulkhead mount as RJ didn't have his done yet.....and wouldn't settle for less NOW......the effin' internet didn't fix them fuchin' pieces of crap......just more bullshit for the acceptability of them.
Zois is not always right, but he's spot on with these.....IMO.
The good news is he's not one to say "I told you so"
Jim Patrick called me back and said he has never seen his product fail like this.
He was very nice to speak with. I think he was kinda shocked.
He doesn't think think I should attempt a repair.
He has requested more pics.
Sent them.
We'll see...
KT
Thanks for the reply Bill. I didn't remember there being two generations of the 1st generation mount? Guess I am getting old!
Post the new pics please.
<best aussie accent> Good on ya mate!!
I think Jim is pretty on there. If the mount failed that badly, what other welds and/or materials are also suspect?
Yeah, that sucker's got to go. It's done. Seein' as you were gonna have to pull the motor to repair it anyway, might as well put a new mount in properly. After reading Andy's eye-witness account of a total failure, I'd pay for the peace of mind. Kindof like a friend of mine's comment about buying single layer nomex/proban driving suits. "The first time you see someone on fire, that three layer nomex suit gets REALLY affordable REALLY quickly...".
-Josh2
The pics are nothing special.
he wanted to make sure the the bar at it's lowest points, under the stock mount location, didn't strike something.
That's the only explanation of such a failure he could think of.
There are some light scratches on there, prolly from the install in my driveway.

Not mount failure. Bar hitting something hard enough to rip it from the mount plate.

Trekkor,
I've always had great dealings with Jim Patrick on his products. I hope things turn out for you okay.
I really think you should go for his wallmount bar. But it's just my opinion.
Bill P.
"Wal-Mart" bar
KT
No offense, but there is no need for any other pictures. That is a manufacturing failure, pure and simple. Even if you hit something, and bent the bar in two, it should never have separated like that........... never. If the weld tore away at the heat affected zone, then you've reached the limit of your materials and you'd see that very clearly. That point of failure would be many times that ever experienced in actual use.
I wonder who PMS has doing their assembly, because they have some "esplainin" to do.
On the list
KT
Holy SH*T!
My newly purchased conversion has the PMS has the quick six mount (not the bulkhead mount). I am going to jack it up tonight and check it out!
Man o Man!
We talked about that
KT
I just want a reliable mount.
Jim wants me to send him my broken one ASAP so we can work out a deal that will allow me to run the next a/x in two weeks.
He has a lot of experience, I can see that.
I don't want to slam anybody.
If a new bar mount will work, I'm happy.

Hi Trekkor,
Send Jim your mount. At the very least he can work with manufacturing on the failure analysis. I'd still go wall mount if you can wheel and deal for one.
Bill P.
I guess I need a break from wrenching.
If he sends me a new bar mount, I might be able to reinstall it without all the motor/trans drop and all that.
the firewall mount in any brand is going to require a ton of work.
maybe I should pace myself, skip the a/x in two weeks, set my sights on May 26th at Thill instead.
it's a bummer, that much i know.
KT
Just a word from a satisfied customer...
I have purchased almost all of my -6 conversion parts from Patrick Motorsports. They have all been very high quality and are performing well. Jim P. has been very responsive and attentive to my questions and orders.
I'll put in yet another plug for the firewall mount, though. It's simple and beefy, and I think a much better solution for a track car.
Easy boys.....
Bill, maybe you aren't the one who should be trying to lift his spirits, what with your recent Burb break in and the ongoing saga of the "beast"
Hang in there Trek. A good solution will come your way. PMS may even sell you a bulkhead mount cheap....Or better yet, get the stock mount from Grant.
I ran my 2.7RS-6 using the stock 6 mount for 5 years of track and AX duty with no issues what so ever.
OK, thanks for the laughs.
I was out side wrenching for a hour or so. ( it's OK )
Got the car off the trailer and up on stands and the engine supported back to the normal position.
Let's talk...
First, this design is good, and I have always like it due to it's simplicity and multiple bolt points, SIX.
The motor CAN NOT fall out...even with this catostrophic failure.
Here's why:
There is a cradle that the plate to motor bolts catch on. It only dropped 3/4".
The bolts would both have to shear off for it to fall! That doesn't happen.
Have a look!

i just dont see why you bother with a BAR mount.
it seems like the half ass way to go - yes, a wall mount will take longer to get in - and the PMS will allow it to swivel down for repairs (good idea!) so why bother futzing with another bar but it wont break.......
DO IT ONCE>DO IT RIGHT
my .02
Now on the the root cause of the failure.
POOR WELDING
I'm sorry, but this welding is not acceptable on any level.
My battery tray has more integrity.
The pictures don't do this low level of workmanship justice.
I promise to anyone you require. If I would have struck this part with a 5#hammer ONE time it would have broke.
Take a look ( If you can )
KT
Attached image(s)
I can see your point there Trekkor. From your pic it appears that those bolts would need to shear or bend to allow the engine to completely fall....
With that being said....the way that piece separated is really scary and a bit depressing. If the piece was truely welded inside and out along its complete perimeter, then how in the hell did the thing completely separate. You would expect to see some of the metal torn or bent in some way. Instead you see nothing but two basically clean pieces of metal. Very strange....It was almost as if the two pieces were never really completely joined by a good penetrating weld.
I agree with an earlier post that this portion should have been made from one piece of metal and then it would be resting on the bar if the weld came loose...no way for the motor to move down....only slight side to side movement.
It gets better ( I mean worse )
Please be seated
Look at all three sides of the mount plate itself.
"Where's the Bead?!?"

Looks like a few tac welds to me... definitely not fully perimeter welded inside and out
PMS should be ing there collective pants right now.
NO penetration there...
I talked to my welding buddy a few minutes ago.
Say what you want, this IS the voice of experience, all his 32 years of it.
He said it can be stick welded back together with 7018 welding rod and no heat treating is required. He spit out some multi thousand PSI of tensile strengh. He will likely put it back together in my driveway on wednesday. I'll have him go over ALL the welds and check it carefully.
I trust this man with my life- period.
KT
I have no doubt that a journeyman welder can put this back together much better than it was before....like it should have been in the first place
My grandfather was a journeyman welder (he taught me when I was 12) and he could stick any two pieces of metal togther just about....
You are lucky to have a good friend with that kind of skill.
Make sure to take some pics during the welding and after it is completed. Will make a good primer for PMS.
Here is mine.

damn who quality assures this product if its got my name on it i wanna check it, its my gettin kicked
I knew I could count on you Mikey.
To save on costs the Bars are not welded, they use JB weld to hold them together.... On second thought if they did use JB weld u may not have had the problem...
If my welder gives it the thumbs up, I'm gud to go.

I don't mean to rub it in in any way, but look at the welds on an RJ bulk head mount
Those are prolly the most beautiful TIG welds you'd ever see
I've had several contacts with Jim at PMS now to resolve this problem both on the phone and in E-mail. He is not dodging me or minimizing the failure.
Please understand that my goal is to get my car back on the road, not tear somebody down.
Jim is concerned with this part failure, you can be sure.
My other goal is to alert him to the poor quality weld work that may be slipping past any quality control that may be in place.
If my car gets back on the road and he can improve his product for future drivers, then all is well.
Sure, I'm mad about the welds and the potential risk I faced and the down time to fix the car.
I'm not mad at Jim. He has made it very clear that he wants to resolve this with me ASAP so I can make my a/x on May 6th.
Support the vendors,
KT
I think any person who has a part failure has every right to show the issue to the vendor. Of course, the intent is to not rub in the failure, but to point out a flaw to help improve their process.
I hope the vendor takes your positive critisism to heart.
Regardless, sounds like you've got the issue taken care of KT...
Tom
Like I said before. Where's the weld? I bet this was a Friday afternoon job - it got tacked together late Friday and then packed up and painted with the rest of the finished mounts on Monday morning.
I'm sure I don't need to say this but - you need to do your own CQ on anything you buy if it's failure would be bad.

He refused to replace it under warranty or offer any sort of credit so it was the last part I've bought from him (after having spent $000s there).
You guys should all really use a bulkhead mount. It's the only way to do it right and the Rich Johnson mount is awesome.

Wow. It's clear in those photos that welding problems are only part of the picture. That failure is an engineering flaw.
PMS's wall mount uses the same cradle mounting flange as the bar mount

Thanks for the link.
I am thinking of a way to prevent the bar from moving foward and thus rotating downward.
If I can fab up a bracket that would be attatched to the firewall so the bar would be stabilized, I may be able to continue.

If anything I would think that PMS wall mount would be more prone to having failure due to it being more rigid than the bar and same engine mounting flange as the bar.

and it has bushings to take up some of the forces.....
The pictures of the Patrick bar illustrate IMHO that it's a pretty crappy design - it puts a lot of force on one section of the bar in torsion... It seems like there is little or no triangulation of this on particular section.
I've tried to illustrate this:

Hmm - this problem looks similar!
i know i'm beating a and grant already hates me, but trek, common, you spent more on GAS to get to the track and back in one weekend than it would cost you to get the Rich Johnson Bulkhead mount.
the RJ mount is extremely sturdy and even allows for two 911 sport mounts to relieve some of that force.
all i ask is that you *think* about it ...

I am thinking about it.

( Grant likes to tweak people. He's harmless )
The problem with those welds is -no penetration!
I have the same problem, but that's a different story.
Just spent time this afternoon talking with Rich Johnson. He is a great guy! Very knowledgable and sounds like he has gone through some development to get his mount to its current design state.
I just placed my order! I highly reccomend anyone planning to go this route to speak with Rich.
Now I have to build up the courage to drop the engine and take this one on myself!
Really sorry to hear about the failure Trek. I was under my car tonight and noticed that even though I have the firewall mount, it's only welded in a few places.
I don't have to whip the dead horse. I told the Trekmeister a long time ago to go with a bulkhead mount, gave him a good price too. "but I got a good deal on a Patrick quick bar", um care to guess why it seemed like a good deal???? Sorry Trekkor, live and learn eh????
I hate to admit that I installed one of those things (before I knew better), but as of yet, it's doing OK with a 3.0. Time will tell.
When I talked to Jim Patrick he said they can and do handle up to 3.6's.
It seems the chromoly tubing may be the root cause of the problem.
Regular tube steel and thicker gusseting with thick quality welds seem like the issue would be settled for all time.

FWIW, on our 935 we have broke the rear motor mount in the "cradle" more than once. Its now part of a pre track inspection, to check the motor mounts for cracks.

Although, after I over engineer the failed bar, we may have a differance of opinions :cool:

We'll do pics of the welding and all that for a certainty.
Whatever comes of this, I'll send PMS my results for his own development decisions.
Do I send him the link to this thread as well?
KT
That poor horse has really taken a beating this go around hasn't he?
Poor dead little guy...
KT
Trekkor, hope your welder buddy has some good news for you.
I see the problem with the PMS bulkhead mount is that it has the same basic design for the connection to the motor. Although there should be less torsional stress on the bar due to it being mounted infront of the motor instead of behind the front of the motor.
Still, what failed on Trekkors was the mount bracket to the motor, and that portion is the same.
No easy answers here as far as PMS is concerned.
Just keep in mind that you want to do this as long as you can, and if the motor rips out of the car catastrophically, you'll be down a lot longer, and the repair will cost way more than a new motor mount...
Eye on the prize...
-Josh2
Not the way your post came across. At least to me.
Sorry if I got it wrong....
So many choices...
KT
I'm going to have my welder evaluate the bar and the welds or lack there of.
If he can make my bar ultra-strong, I'll run it again and keep a close eye on it.
If I can get it to hold up for the rest of the driving season I will leave it.
It it blows up again I will use something differant.
What would you do?
KT
Any further word from PMS?
I think he's a morning person.
Pretty funny.
I don't buy it.
What, I'll be the first?
My motor should have fallen out Saturday.
The bar can't fail any worse.
The WHOLE MOUNT PLATE WAS SEPERATED!!!!
kt
Ok, I have kept outta this because I have no experience with installing a 6 mount...either style. However, this is getting rediculous....we all know that Trekkor will do what he wants until he proves himself wrong. There have been some cool/resourceful things he has done. However, in this situation, I would have to agree with the guys against fixing, using, or considering this mount bar system. The mere fact that you are racing the car seems to me a considerable reason to pass on the cheap, easy mounting system and go for the most realiable, proven, system...i.e. a bulkhead mount.
It costs money to go racing and a lot of that is saftey. While in this instance, the mount bar broke in a location that kept the engine in the car, what is to say something worse won't happen again. If you look at the failure, it occured at the weakest point which happened to be at the point where the bar is under the most torque loads. If you strenghten the mount in this location, you transfer the weakest point to somewhere else. I feel that this will place even higher loads on the engine mounts in the tub as they are absorbing all the load. In my opinion the design is flawed in that it is using the motor itself as a structural contribution to the engine mount...i.e. the torque induced from the offset forward. This cannot be overcome in this design and therefore should be avoided, especially if the car undergoes significant weight transfer and high speeds. If you are going to do something, do it right the first time and focus your time/energy on driving the car fast instead of worring about a serious incident.

Trek, if you need a reminder of what broken tranny mount ears look like stop by the house. Personally, I wouldn't risk a motor and a race prepped tranny just to prove a point.
But if history is any factor, your welder will fix it and you will run it. Hopefully, it doesn't cost you your driveline.
Looking forward to the pictures of the repair.
I'm sorry you ran into this bad luck. Trek
If you won't look at this issue from the standpoint of the grief another failure will cause you think about what might happen to other people. If you have a piece of equipment on your car that is suspect you should not race. You put other people at risk. Try to predict when that mount might fail next. You can't. Try to predict what might happen when it lets go again. Are you absolutely sure you will be able to control your car? Course workers have a right to expect that drivers will not put them at avoidable risk. The odds are probably 1000 to 1 that nothing will happen but if you can make that 10,000 to 1 or 100,000 to 1 by removing a part that is known to fail you must do it.
Sorry I'm coming across as holier than thou but if I was teching and I knew you had a suspect engine mount I'd fail you. I watched Craig (Camp 914) fail Bruce Allert for a stripped wheel lug. Another guy came over and said to Bruce it was Bruce's call if he wanted to run and Bruce said it wasn't safe. The other guy was trying to be nice (Bruce had driven a long ways to run) and both Craig and Bruce were right to disallow the car.
Fix it right and have piece of mind.

Because he just spent the Rich mount money on a roll cage
It's not about the money...
What is it about then?
OK, now I'm talking to myself.
Well, what is it about?
Good question.
KT KT
I climbed under my sixer last night and took a gander at the PMS bar mounted on my conversion. I agree that the bar design places a torque stress on the plate/welds as it is forward of the centerline of the stock 914 4 cross member mounts.
I don't plan on racing the car, but I may decide to do an AX once in a while. My question is: Should I trade out the bar to the PMS bulkhead mount (bolted) or just leave it alone?
The Rich johnson mount would be the way to go but my chassis is so clean and nice, I don't want to mess it up with welding. (Not to mention the down time - NO MORE JACK STANDS - at least for a while )
Opinions?
KT -
If I were going to race my car, I'd replace the PMS bar that I have, with the rich Johnson style welded bulkhead mount. Just my opinion. I think I just answered my own question - I think I'll put on the PMS bolted bulkhead mount.
Another thought -
I'll bet that the Stanford or Berkeley engineering schools could (would) be interested in doing a metal fatigue analysis for little or no cost. I would ask and then ask PMS if they would pay for it. I would be interested in seeing how the stresses are distributed through the mount and where the metal is most vulnerable.
why are we still talking about this?
EVERYONE said go bulkhead.
Just for another data point to this discussion. I started with the PMS bar when my 914 was converted to a six. It was the generation 1 bar and the car was track use only. On the first track event my transmission shifting became very difficult. Reason.... the PMS bar had bent dropping the engine and bar down on to the shift rod binding it. The bar was replaced with another and the same thing happened. After much frustration I went to a bulkhead mount and have been trouble free for years. If PMS says their bar is not for track use ...BELIEVE them.
I found posts #'s 38, 65, 114 and 171 to be most helpful.
Thanks
I beginning to think we're gonna spend more time talking about a bulkhead mount than it would take to install one.

He's convinced they forgot to weld it.
As to the fix, he wants to use 3/32 cro-mo rod and TIG it on Saturday afternoon. Then we'll have dinner
He said, "piece of cake" and "it won't break".
We'll see.
I see myself also ordering an RJ mount and having an install party with Grant when he's ready. Two in one day
KT
In the mean time I will invent a diagonal brace that will make it impossible for the bar to move downward.
KT
If you do attempt to repair the quick six mount, I would take a look at the other failure shown in this thread where the mount ripped the tubing just past the weld. You should print out that pic and show it to your welder for reference.
Your welder may decide to take a look at that weld as well and do some reinforcement.
hey trek, just in case no one has mentioned it yet, i'd rather go with a bulkhead mount instead of trying to fix this thing ...
Andy
Yes.
KT
I'd get one of Rich's
Wait... I DID get one of Rich's.
WWAaD?
I was just wondering...What do you guys think about the idea of me using a different style of engine mount other than the PMS bar mount I have and was considering repairing?
I heard they make a bulkhead style or something. Anybody heard of this?
KT
Might wanna check around. I heard Andy installed one of John Richardsons in his car and it bent the whole thing up when he welded it in...
Spit and rubber bands would be better than what ya had...prolly longer warrenty too....
Now we are going from the sublime to the ridiculous
i woulda thought the first 9 pages had you convinced. apparently not.
so, i vote bulkhead because eric shea did it, and he is my hero
That popcorn guy cracks me up...Why does he look around before eating?
I'm gonna try that myself someday.
KT
Trekkor,
I vote that you sell the 914 and buy a 911 GT car like me!
Mucho faster than a 914, handles better than a 914, and they don't break!....
Bill P.
(I go both ways....mid and tail! )
And Bill, who is it that is still building that killer 914? I think it is called the Beast or something like that.
Now I'm convinced. Sell the six and buy a Raby T4.
Nope, Bombay Saphire GT
KT
I did check my mount, as I do regularly. I expect there could be a failure, but don't necessarily expect one.
It's fine so far. If mine fails, I'll attempt a fix (I have some ideas for the reinforcement of the piece) and then replace it with a firewall mount if it starts to fail again.
You guys can be pretty dramatic on shit like this. I agree that the torsional stresses on this bar are significant, but to imply the problem can't be rectified with additional engineering is a little silly.
The original 'Quick 6'(from another company) mounts never fail and they have similar torsional issues. The only difference is that they overcome these stresses with large amounts of thick steel.
I'm not affiliated with PMS, but have found their products to be of high quality.
Clearly PMS has some nice products. What I can't understand is how they could take any failure of their products lightly. The world is full of talented engineers and fabricators that can literally make anything you can imagine, all it takes is time and money. The only thing that separates one company from another is reputation and track record. As much as I try, I just can't understand how ANY company could let something like this happen without being profoundly concerned and exceptionally accommodating.
PMS should have a new bulkhead mount in the mail to you at no cost, as a goodwill gesture. Look at all the trouble you have to go through because of the failure of their product. Sure, they can say they fired some crack head welder a while back because of shoddy work, but it's about taking responsibility for what you produce. Every time we buy a product, we put our trust and faith in the company that produced and sold it. I'd hate to think that in a market as specialized as Porsche conversion parts that they feel it's ok to turn a blind eye to their client base.
How many sales do you think they've lost every time a thread like this comes up? How many customers will they never have because Mike Z. had a poor experience with them? Unfortunately it's a case where they have enough customers, and evidently enough money coming in, that they don't have to care about every customer. When your name is on the part, I'd think pride should be more of a concern than money.
You know very well that PMS is following this thread, but we've never heard a word from them, and this is hardly the first time something like this has happened. That's because time is money, and no one is paying them to care about what people think. Every once in a while we all need to take a step back and remember that it's not about the cars, this is all about people, and their passion for cars.
Ok, rant over
how many 6 mounts are actually sold each year(new)? split the sales #s between rj and pms, and it's slim pickings for the manufacturers. my guess is there is a bunch of new stock, sitting on shelves from the last production run (when ever that may have been). as a vendor, you would think all items would have to be blasted, welds ground out, rewelded, or just thown in the recycle bin. start fresh. forget a q.c. inspection.
there is obviously a flaw in the manu process. i've seen concrete tilt walls (we're talking tons) with relatively small attachment points, welded with square bar stock and stick rods, backed into with trucks, and they don't fall over. i wonder if pms does the work in house or if it's farmed out?
k
Maybe I missed it, but did PMS respond to you yet Trekkor??
We've not spoken in a while.
Since I told him I wasn't returning the broken bar, it seems he's lost interest.
I've called and left messages. He called back once, but I was away from the phone.
Maybe I'll call him again today.
I'm not really sure what I should expect.
I really think he needs to use a bar and gusset with thicker guage metal.
Or include a bolt on diagonal brace that goes between the mount cradle and the firewal to prevent torsional movement.
That's what I plan to do after the weld repair is done.
KT
Several here have stated they've seen 0 failures with the Rich Johnson mount. Well, I saw one. It was on a car with a hotted up 3.0, and the failure was cracking on one of the mounting ears that bolt to the engine. It was fixed with a reinforcement plate before anything bad happened. So, they CAN fail, even if it is a rare thing. Trekkor's 2.0 also doesn't put out anything like the torque of a 3.0, either.
so i'm driving down 880 in the 914 to work this morning, nice morning, top off, cruising at 60 in the middle lane. i'm enjoying the ride and the world seems to be a good place to be. get a few thumbs up from strangers. a kid in a dodge ram with flowmaster exhaust thinks he's driving a race car and wants me to turn 880 into a drag strip during thursday morning rush hour. i laugh at him and he takes off. i feel good knowing i made his day. he raced a porsha and won, i'm sure it'll be the talk of the day. traffic was light and taking the offramp onto 92 at 65 put a big grin on my face. it was high tide and only a light breeze over the bay. the water almost looked like a mirror and the mist had yet to be burned off by the rising sun. the air smelled fresh and moist. i watched a few airplanes heading towards SFO as i crossed the san mateo bridge. it's amazing how beautiful this place is, especially in the morning. and the fact that i was in my 914 with the top down didn't hurt either. got to work in time and got myself a fresh coffee from the armenian coffee shop around the corner. someone had mowed the lawn last night and the fresh cut grass smelled like spring. it's supposed to be in the 80s today. can't wait to get back into the car for the ride home.
what was this thread about again?
Andy
OK you guys are scaring me. Where do you buy the RJ mount and how much?
T.C.
Wow,
12 pages ont this subject. I bet PMS hasn't sold as many bars as people who have commented. I have one I bought new from PMS 2.2 with no problems. My friend also runs one on his PCA-GT5s 914 with a 2.2 and 180 rwhp. No problems for 5 years of abuse.
just my thoughts,
van914
I agree the PMS bulkhead is built of the same strength materials.. but I think that the forces on it are quite different.
having that underbar reach behind the motor and take the force/twisting of the motor rocking forward back exerts more force than the simple up/down (without leverage) that the bulkhead gets.
I'm certainly no engineer, but I haven't yet heard of a single PMS bulkhead failure (and there is a lot of ancedotal about bar failures)
The factory bulkhead is small and puny, but works pretty good for what I theorize to be the same reasons.. less leverage, less force
brant
Bad welds will fail both of the POS bars... If the quality control at POS is not there or he called in sick that day...The welds may not be what they should be and they will fail.
RJ mount all the way..Get-it and forget it
This is prolly why I'm stubbornly trying to fix mine.
It wasn't welded...
Even with that it survived 20ish a/x's and 9 track days.
I'll give it one more chance.
KT
2 points to consider:
1. This thread may never die.
2. If my bar breaks again do you really think I'll tell anybody.
KT

Lemme see if I got this right........
You put a part on your car that was missing a weld?
Yeah
What's the big deal?
KT
Speaking of weight savings. In talking with Rich he indicated that I could cut out the standard 914-4 engine mounting structures which allows for better access to engine and cuts weight.
Trekkor, This is son of Frakenthread. ...It just wont die!
But what if you want to go back to a /4?
Dave
So you have a match for the other VW parts.
With the stock FOUR mounts, yes I thought of that already.
If my ( when my ) SIX blows up, I can slap the FOUR back in the car with carbs and still play while tracking down another SIX.
It appears $1500 for my complete 2.0 FOUR is to pricy for this crowd, so I'll keep it around until I need it that one day.
Let's not talk about that anymore though, OK?
KT
NO, no! We can keep this topic alive as long as we please.
It's blowing up my SIX I'd like to forget.
Whoo hoo
KT
"Quite a turn, unexpected, this thread has taken"-Yoda.
I made a call to a certain friend of mine who owns a parts house that knows the seller of the mount and suggested that he tell the seller of the mount to pull his head out of his ass and back his product....the parts seller said that was a good idea and would pass the suggestion along.....let's see what happens....
I wonder if this thread has been "seen by seller".
I plan to send the repaired mount pics directly to him with a follow up phone call.
KT
That's true. I didn't want to deal with shipping , waiting, inspecting, etc.
I inspected this bar prior to install and when I had it out for the racing trans swap.
Looked good both times to me and others.
From an e-mail I sent on the 25th:
"...Truthfully, I'd have to have him ( my welder ) go over any replacement part you may be willing to offer.
After what I found yesterday, I was completely shocked at the lack of welds."
After that statement, no further contact has been made.
Am I mean?
KT
The pics he gets from me will show what *real* welds look like.
KT
Trekkor,
Sorry to see this. All I can say is, it lasted a lot longer than mine! Here are some shots of how mine looked after two autocrosses with my "monster" 2.0L motor and a 205-50 R compound khumo.
Here's how I attempted to fix it. I still didn't like it. Under full throttle over bumps I could hear the engine revs jump as it flexed.
Went to a Rich Johnson mount. That thing is SOLID. Anyone interested in buying the above mount for $125, please PM me. If you are only running on the street, I believe this mount will be fine.
Kelly
I just ground all the old "welds" off.
My welder picked up the Cro-Mo TIG rods.
Tomorrow night
KT
...well?
Since you asked.
I just got home, shot a few pics.
Had a nice dinner of lamb, chicken, shrimp, potatoes, asparagus, brussel sprouts, salad and bread.
Chocolate truffles and tira misu. (sp?)
Oh, the welds...
Turned out fantastic.

Last.
Extra stitch welds behind the plate.
All this was done with a fantastic little welder. Totally portable.
A Miller 110/220V TIG/Stick no bigger than a small mailbox and weighs only 10 pounds.
This machine can do work like the machines mounted in a truck bed.
I want one.

Looks good. Judging from the other pictures in the thread I'd keep an eye on the welds directly on the bar to see if the bar starts tearing/cracking. But that plate isn't going anywhere.
Saw those little TIGs at the welding supply. They're great little units, I almost bought one myself, just because they were so dang portable.
That's a real good looking repair. I'll be interested to see how that holds up for you. As Mark said, and I show in my picts, most of the failures I've seen have the bracket ripped off of the tube. That's why I chose to add pieces to go all the way around the tube. Yours is the first one I've seen have the plate separate.
Kelly
Looks good. I would echo the concerns about the welds on the pieces that attach to the bar. If one set of welds were bad wouldnt others have potential of being bad as well?
Glad to see this fixed in short order. Will you be back on the road this week?
My car is in for alignement this week. I fixed my clutch adjustment and it shifts great now. Still a little bit of gear grinding in 1st to 2nd, but nothing terrible like before. And I have new throttle cable, pedal linkage and Engmans great looking aluminum pedal board. All my excuses should be gone by the next event.
I put it all back together in about an hour and a half.
I only had to re-connect the throttle cable and the shift rod. It slipped right back up in there.
Even cleaned the underside of the motor and drove it.
KT
I just e-mailed PMS with my repair pics and intentions.
I have not asked for anything from them due to the failure.
Just a FYI and I mentioned the thread here on the clubsite and the overall perception of his mount by the members.
KT
Tell him I said Hi......
I will.
