My 3.3L Subie Conversion Thread, Got me some 914rubber stuff Options

[Chris H.]

Chirs my mistake. I had an air leak on the vain in the intake. I was thinking if yours was sticking or leaking air that might be the shuttering problem. The vacuum valve it hooks up to had a crack on mine so it wasn't fully opening or closing the "air splitter" in the intake.
The trans pulse should be rock solid. The trans had one or did you have to put it in? Some of the ty756 trans didn't come with it and the have no gear inside. If you have a wrx tran it's probably a ty755?

Ah that explains it. That would definitely cause issues. I decided a while back to switch back to the stock intake just to make sure I eliminate any potential compatibility problems. The engine ran fine in the SVX. Just something simple I'm sure. The trans is a 2006 and the gear was in there before. Pretty sure it should work the same way.

[Chris H.]

Measurements for you Christopher...these are approximate.

About 28" wide



The engine itself is just under 22" deep, then you have to add the snorkel for the stock intake manifold, which would add about 4" or so



The engine and trans are about 48.5 front to back, again, add 4" or so for intake.



The height of the engine is tough because I pulled the manifold off but I would guesstimate it at about 26" from oil pan to the top of the manifold.

Thanks to both of you!

[Chris H.]

And then I did a tiny amount of work (IMG:style_emoticons/default/biggrin.gif) .

Got the timing belt cover off, pulley, etc:



The leak is right here...VERY small one but I hate oil leaks.



At first I was a little panicked because that black stuff looked like JB Weld....which would mean something bad. But it's not. It's black RTV. Scraped right off and is pliable. Someone tried to stop the leak temporarily with it. Any idea how much work that was in an SVX? Brings lazy to a new level.

Once that engine is out most everything else is easy; except diagnosis of course. p.s., Received the controller, Chris Nice neat little package. Good tip. Thx. (IMG:style_emoticons/default/beerchug.gif)

[Chris H.]

(IMG:style_emoticons/default/thumb3d.gif) Cool man. Very easy to install. Remember you'll probably have to adjust the thermostat a bit. I'm sure you can see the dial on the housing with temp #s. My fans came on way too early initially. Think its set at 165 from the factory which means they wont go off until the temp gets to 155...so...not until you turn the car off. (IMG:style_emoticons/default/biggrin.gif). Put the sensor right by the HOT inlet on the rad. Then a few tweaks and you'll be good. I doubt they'll come on much until you kick the AC on. Pretty sure we can stick with the rad hoses we have now after all (IMG:style_emoticons/default/beerchug.gif) .

After reading the wiring instructions I see why some people were claiming them to be "DOA". The Futsie's probably missed the part where "neg" fan connects to "pos" on the unit and wired pos to pos and neg to neg instead.

[Chris H.]

Totally stumbled on this one but it's a good lesson. Check the crank and cam angle sensors! The car ran fine so I ASSUMED they were OK.

There are two Crank Angle Sensors that are located on top of the oil pump right under the alternator next to each other. I was removing them to take the oil pump out and one of them just didn't want to budge. The outer metal sleeve had come loose and was stuck inside the hole. I tested it and found the sensor was bad so I manhandled it out.



Looks like a small amount of water must have gotten between the sensor and the pump housing:



That's the one area I didn't mess with when I resealed the engine (of course).

When you test these using an Ohm meter it should read ~2600. The other two are very close...



The bad one...nothing...



These are very simple magnetic sensors, they are technically all interchangeable. The only difference is the angle of the plug.



Of course the one I need is #1, and the plug end is pretty unique. Just need to do some searches to see what other Subaru sensor is close enough. You can find these for $20 -$30 each. Tempting to replace all 3. Definitely not spending ~$250 for the SVX one.

[914forme]

Chris I have 1 complete set, and the two on the engine, the cam sensor was trashed on my mockup engine. If you don't find one I can pull them next weekend. I am traveling this week for work, will be back in town next Friday.

[Chris H.]

Thanks so much Steve. Very nice of you. I'll definitely let you know but will try to use the Legacy ones first so you can keep those as spares. The price for a new #1 is RIDICULOUS.

[a914622]

I have heard rumours the Nissan crank sensor plugs in from the top or 45 deg like the svx. I have not confirmed that but I will have a look next time I'm pocking around the wrecking yard.

[Chris H.]

Interesting. Thanks Jeff. I ordered a couple of Legacy ones for a whopping $16 each. They are the OEM replacement on Rockauto so not the el-cheapo ones.

Slight progress while we wait...

Oil pump is off. Never resealed in 21 years. Seems like it might have been leaking slightly from both the seal around the pump housing and the front seal around the crank ( I think referred to as the front main seal). I got the seals I need in the Subaru reseal kit, just never used them.



Look at the crap behind that thing.



O-Ring is not very pliable. It broke later.



Got the RTV removed from both surfaces. RTV is the OEM way to seal the oil pump. Same with the oil pan.





Tomorrow we clean the gunk off from on and behind the oil pump, re-seal it, get the timing belt back on. I'll detail the procedure for doing the timing belt when I reinstall it. Easiest one I've ever done (3 times now (IMG:style_emoticons/default/biggrin.gif) ). Non-interference too. It's gonna be flying down the road in no time (IMG:style_emoticons/default/beerchug.gif) .

[motoTrooper]

I am working on my 3.3 vicariously through you! Great photos and description, you are saving me so much time when I actually get my donor car. Looks like that Celica radiator will fit the Scorpion too as the old one I pulled today is 31(l)x10.5(h).

I do not wish to hijack your thread but want to share pics. So shall I post a link to one of the Lancia/Fiat sites that I have build threads on?

Best regards -Christopher

[Chris H.]

Sure that's fine. Go for it.

[76-914]

Great progress Chris. So tell me, I've never used siliconed as a gasket. Is the proper technique to apply and tighten or apply, tighten some, let cure then complete the tightening. (IMG:style_emoticons/default/beerchug.gif)

[Andyrew]

The Audi factory manual for the oil pan says to torque the bolts to 5lbs the wait one hour and torque to 10lbs.

I did the same thing for all my other things I RTVed. Hopefully it works....

[Chris H.]

Yes that's it Kent. I'm gonna pick up some fresh RTV today since I'm out so I don't remember the exact timing but you apply the stuff, put the parts together but only tighten them a bit, then finish torquing when the stuff is almost completely set.

It'll work Andrew, believe it or not (I was skeptical). My oil pan has held up fine for 3 years.

[ThePaintedMan]

That's good info guys. I was wondering what the factory procedure was with the RTV, as I had never used it on two machined surfaces before. I saw that the factory RTV was the orange stuff when I pulled my oil pump, however, I'm inclined to go with the black RTV - more oil resistant. I really like the grey/Hondabond/Yamabond, but it might be a little too thin for this application.

Yes I went with the black on my oil pan George. Might use it on this too.

I love Hondabond! Some of the best stuff made IMO.
