My First Hiccup, finally put this to bed after the 3rd try Options

[76-914]

When we returned from Rt66 '16 I pulled my exhaust system down for a little trimming and noticed water in the left bank muffler! (IMG:style_emoticons/default/WTF.gif) We did drive through a ton of water on that trip. Then when returning from Costco yesterday it acted as if it were starved for fuel when it stumbled during acceleration. The fuel filter was the same one that came on the engine so I ordered another one. When I looked at the filter to check which one I had I noticed the coolant level in the expansion tank/reservoir had dropped. Well, there you are. Head gasket time. Now, I'm wondering if the stumble was due in fact to the head gasket failing? Decisions; should I fix this one which presently has ~ 185K or buy a JDM replacement. After perusing the net I found a few peep's whose JDM experience was less than stellar. Apparently it is a crap shoot as to what you get and the 40-50K avg mileage is (IMG:style_emoticons/default/bs.gif) . So, for about 1K I can pick up another engine and hope I bought a good one or open this one up and hope that is all it needs since it wasn't overheated. What does the the Wasser family think?

EDIT: It's an EZ30D 6cyl

Got the engine back in Sunday and she fired right up. I still have the issue that precluded the engine pull which is a fuel starvation issue. It falls on its face under acceleration. Ordered a fuel pump last nite. It runs great except the stalls but when I put it on the rack I found an oil leak on the rear chain guard. (IMG:style_emoticons/default/headbang.gif) I believe I didn't use enough sealant but we shall see. Given my prevailing piss poor attitude I ordered another engine. I'll throw that sucker in and take my time with the sealant when I pull old number one down again. I want to keep it in waiting. (IMG:style_emoticons/default/beerchug.gif)

If you get your fuel system figured out and it's running great, how big of a job is is to fix that leak again - another engine pull? Even if so, it doesn't seem to take too long for you. (I know time is compressed in your thread so 'not too long' is a relative term!)
But if you've got the rest of it buttoned up and running well... well, that's just me!
BTW, Mike Bellis just bought an AEM fuel pump and apparently loves it!

I R&R it w/ a stock Suby pump and it is working fine, thus far. If it burns out within 24 mo's I will go that route. (IMG:style_emoticons/default/beerchug.gif)

Hah! I flew w/o one of those for years until one day I took my daughter up and noticed my airspeed was 0. I was flying off a 1600' grass strip with a 50' tree on one end. Needless to say I landed at a large airport a few miles away and cleaned the mud daubers nest off my pitot tube. After that I bought one. (IMG:style_emoticons/default/headbang.gif)

First call on take-off... "set take off thrust". Second call is... "airspeeds alive". (IMG:style_emoticons/default/laugh.gif)

Now you tell me!


Round 2 - Took time away from the project these past several days to attend to, shall we say, life. No sense in whining about problems, right? With that said I'll move along. The newer engine is in and running but not w/o a hitch or 3. (IMG:style_emoticons/default/confused24.gif) I forgot to release the Subaru "pull type" throw out bearing so I lost a few hours reacquainting myself. (IMG:style_emoticons/default/headbang.gif) . The alternator had a bad bearing so I used the one off the other engine. I used the smaller AC compressor that came with the engine but I will need to change the size of my suction line as well now. And as it turns out, the TPS from either engine works fine although they have different part #'s. (IMG:style_emoticons/default/confused24.gif)
When it first fired off it belched an orange-ish cloud and settled in with a rpm of ~1200. So I switched the TPS back to the one that came with it and tried again. This time the idle was ~2800rpm. (IMG:style_emoticons/default/new_shocked.gif) . After I cleaned out my pants I settled down enough to find that I had not reconnected the TPS plug so the ECU never saw it. After I reconnected the TPS plug the idle returned to 1200rpm so no difference. After 2-3 minutes of idling it began to hunt. Now (IMG:style_emoticons/default/sheeplove.gif) what? (IMG:style_emoticons/default/headbang.gif) I'm hovering over the engine when I felt the tire spin against my leg. Lowered the lift enough for the rear tires to make contact with the concrete and it stopped. My take on this is that I am running the USDM ECU which only support an automatic so the VSS sender on my transmission works BUT it's looking for some torque values that the 5 speed manual trans isn't sending. It compensates by raising the idle a bit when run @ < 10mph. I figured that I'll drive with the high idle until I figure it out. My previous experiences w/ DJet had trained me in the fine art of driving with high idle syndrome. (IMG:style_emoticons/default/av-943.gif) So, I hop in and get about 300 yds down the road and it starts with that hunting (IMG:style_emoticons/default/stromberg.gif) again but this time with vigor. (IMG:style_emoticons/default/WTF.gif) (IMG:style_emoticons/default/ar15.gif) (IMG:style_emoticons/default/headbang.gif) Now I'm ready to kill something. I resigned myself to re-installing good ol' number 1 but decided I'll drive the piss out this thing until I get the other one back together and installed. This is where it gets weird. I've developed a habit of closely monitoring the tach on the upper end so that I can avoid the hard stall that comes at 6600rpm indicated. I say indicated because I am running the VDO Interrogator Tach. The new engine hits 7000rpm indicated before I shift. I didn't want to run past 7000rpm, either. Odd that with the same ECU the new engine rev's higher. (IMG:style_emoticons/default/confused24.gif) This however stumps me. After the 3rd or 4th hard pull the engine stopped hunting and the idle returned to 500-550rpm. For now, I'm going to assume that I had a presence along for the ride and he put a SLITS tune on it's ass. I have no other explanation. (IMG:style_emoticons/default/shades.gif)
When the engine was out I cleaned up the wiring and labeled everything. I still need to draw a proper schematic that represents the cars current (NPI) wiring layout.


Now that I have the other engine on a stand I'll take my time sealing it up and keep it as a spare.





I also took the opportunity to paint my cradle as it had been sporting primer these past two years. I decided to strip it down to bare metal and inspect for cracks before I blindly threw a few coats of paint on it. I used PVC purple primer instead of Magnaflux. It works pretty well, is cheaper and can be used for plumbing chores later. (IMG:style_emoticons/default/beerchug.gif)





And here sits the newer drive train awaiting it's new home. (IMG:style_emoticons/default/biggrin.gif)
