Resolved 2G Engine Rebuild

[RubyEclipse]

Hello everyone! I just purchased my 1996 Eclipse GST a few months ago, had some issues with a few different things. Most recent was car was smoking and running very uneasy, so I decided to pull the engine. I am going to do a full engine rebuild-ish, I bought new wisco heads, still looking at the rods I want, if there’s anything anyone thinks I should buy and upgrade I would love help! Trying to push more power but not an insane amount seeing how I want this to be more of a daily but not quite. Thank you guys!

Ok, was just wondering. They’re tightish, not the most but they’re not loose. I’m getting the attachment for the hose tonight, I made the BLT thing at ace and I have it all set up waiting for an attachment for my air compressor. So I will let you all know how it goes.

The pipes sometimes aren't glued well. I used to have one come out of the intake with the hose. It's not a big deal. I think you're on the right track

Made my own little thing, but it doesn’t seem to be working, that or there is just no leak. I plug the compressor thing in, I’m pressing the switch but it’s just leaking? It’ll start out at 60 psi and go down to zero super slow but still. Am I doing this wrong? Thank you guys.

Use regulated air. Give it 20psi or so and let it keep going. Feel, look, listen for leaks. Soap bottle helps.

Regulated air?

 

[pauleyman]

Regulated air?

Sounds like you're just pushing as much as you can. Do you have a pressure regulator on the compressor?

No, sadly I don’t think so. Can I go pick one up somewhere?

Look at it. Most of them come with one.

Ok, I will.

 

[Justin DuBois]

Ok, I will.

If your compressor as a dial pressure gauge on it, look for a knob (big) to turn. The knob typically sets the pressure in the hose. Turn the knob down until you have 20 psi on the dial on the compressor.

Got it, I know exactly which dial you mean, I’ll try that tonight or tomorrow morning.

It will take a little bit to fill the system with air. If you are pressing and holding for a bit and the pressure bleeds off and the gauge drops back down to zero, then you have a leak.

What you want to do is have the air being supplied constantly without you having to hold the trigger. That way you can crawl around and listen/spray at each connection to find your leak(s).

Set your output pressure to 20psi and either tape the handle/trigger down on your hose so you don't have to stand there and squeeze it, or have someone else hold it to free you up to investigate for leaks.

Ok perfect, yesterday I didn’t really hear anything, are these leaks going to be very quite)

 

[CKOPOCT]

Most likely. Kind of like having a leak in a tire - if it's hissing it's really bad. Most of the time the leaks are only noticeable by spraying a soap solution and spotting the bubbles.

Got it, perfect. I’ll do this today then, thank you so much!!!

So I really, don’t think I’m doing this boost leak test right, I think it’s coming from the belt side, i had a serpentine belt snap and that’s when I remember getting all these problems but it could’ve been after. But whatever I’m doing right now isn’t working for this test. If there’s anything else I can start looking for or fix let me know. Thank you guys. : )

Ya know, I kinda had trouble grasping the whole ‘boost test’ thing, but I have never had a turbo..strange because the intake swings from vacuum to pressure real quick like, so, that being said, what you are looking for HAS TO BE IN THE INTAKE.. from the turbo inlet to the pistons.. I don’t think there is anything on the belt side that would be affected.. could be an intake mani leak, maybe a fuel injector, Intercooler connections or the throttle body.. that’s where I found most of my problems, the TB.. BISS o-ring, shaft seals and such.. also found a massive leak at a hose connection that I thought I had tightened really good.. gotta be able to keep some kind of pressure in the intake to search for leaks.. I used a stethoscope (after cutting off the membrane fitting and using just the hose to poke around) and it worked great.. the other way is to use a soapy solution, that way you’ll get a cleaner engine bay when you’re done..!! , bonus..!! Good luck and don’t get frustrated, takes precious time.. let us know

I put earlier that oil got a bit overflowed I think, it was running in the tubing just about everywhere, all up in the intake manifold down to the turbo inlet. Could that be something? Should I take off the TB and rebuild or clean it?

Might hope for a wise man to chime in.. my understanding is that a certain amount of oil is present in the intake because of blow by.. this might be a learning session for the both of us..

Yeah, all of this is a learning session to me

Oil in the intake is not "normal" but there are some reasons for why you might find some. A thin film of oil is no big deal (a little blow by), but if you are finding puddles collecting in the corners of all your intake pipes, and intercooler, or enough oil to burn smoke - that would be bad.

In general - Oil runs/collects down hill from the source. Oil also collects downstream in the intake. Keep this in mind, and you can work backwards from where it is, to find where it is coming from.

Knowing where oil channels and seals are in the mechanics is really helpful here. For example - The turbo has an oil feed and drain (and a coolant feed and drain) A Turbo can fail and leak 10-100psi oil into the intake. Even under boost the oil pressure is higher than the charge air, so a turbo is a common culprit for oil in the intake.

If your intake (before the throttle body) is dry but you are still burning oil, this tends to point the finger at the head. Etc..etc..

If everything is oily - you would do well to take apart your IC pipes and IC, and clean them inside and out with dawn soap and water, then wipe/dry everything and put it back togeather clean so you can do better investigation of the source.

Thank you Justin.. that all makes sense to me.. I found some oil and started to wig out but I had read in another thread that some oil is ok, but like you said, puddles is a bad thing.. a learning curve.. hehe

Alright everyone so, today I sprayed water, did the turbo stuff, couldn’t find as to why my rpm’s are doing that anywhere. Thought I’d fire her up and take her for a spin just cause, drove about 20 minutes without one issue. At all! She drove amazing and man did I miss that car! was pulling into my house after grabbing more coolant, a belt had slipped off the alternator, no biggie. Going to replace all of those belts anyways. Letting car cool before I add coolant to top off, thing that’s scaring me right now, is there’s oil on top of my valve cover next to my plugs, not a ton but enough to worry me. I have no idea what I did, but she’s running absolutely amazing! Tested every gear and boy she flys!!!

Can’t even tell you guys how excited and thankful I am.

Oil in/near spark plug wells is usually a VC gasket. It could also be cracked. Classic mistake is to crank the bolts down tight. A VC need only squish the gasket, not bottom it out tight. Also, Oil fill cap gasket may be dead.

Dang it. I think I cracked it. I was praying I didn’t hear something but I think I did, it’s super super small, am I able to put some of the strong glue on it or no?
