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!

Did you take pictures and look thoroughly? No excessive cam lobe wear, lifters properly seated, no broken valve springs, etc. Or maybe some debris floating around up there. I'm almost certain that isn't a bottom end issue. It sounds like something right underneath the valve cover is the problem.

I will pull the cover and check. I didn’t see anything, but I am blind. I’ll post a picture and you guys can tell me if you see anything.

I thought it sounded like it was in the head too, but actually being there is different. No lazy or broken valve springs are there or a single rocker that decided to exit, stage left?

I will definitely check, great use of words.

I took off the cover and see nothing out of the ordinary. Still making that awful noise, I tried spinning in by ratchet, it will spin. But it feels and sounds like something is rubbing, there’s creaking like a door in there. But also, I hear air escaping with the valves. Don’t know if that’s good or bad, when turning by hand I do feel and hear things in there.

It is hard to capture on video, but I try my best.

what if something was loose inside the bell housing, rubbing on the clutch, or flywheel? seems rpm dependent, or is the sound over on the utility belt side, like a bad alt bearing, or the screws from the alt housing are backing out

Maybe put your phone on video pointed at spots unseen, and make the noise, see what has not been seen

I want to check the bell housing because i felt my clutch like being pulled on in a sense, or something was rubbing against it, i felt something throw the pedal for sure.

Start with a flashlight and remove the clutch fork boot and peek inside while rotating the crank slowly by hand. There is also a 3 bolt cover to inspect the back of the flywheel - but I think you need to take the downpipe off to see it.

How do i do that? Take off the clutch fork that is, i know how to take off the plate on the bottom so i will take that off.

Clutch fork boot, it's the rubber boot right down where your slave cylinder is on your transmission. I believe you just pull it back gently and it'll pop out of it's little groove.

Got it, i thought that’s where it was. Didn’t know if i needed to disconnect something, i will take it off and check it all out. Thank you!!

 

[RubyEclipse]

I went under and tried to check out the transmission, I didn’t see a single thing. Like I couldn’t see into the transmission from below because of the flywheel, and the boot was blocked off by whatever rod was coming out. I did sit under it and try spinning it is sounding like it’s somewhere over there towards the starter. It makes noises wherever I move it super fast like back and forth you know? I can’t say for sure it is over here, but it sounds like it’s by cylinder 1. This is my guess, but it definitely sounds like it’s over there.

I’m looking more towards the back of the block, and maybe even the transmission side. Whatever it is, it seems to tick with the slightest moments of the crank. If I barely go back and forth really quickly, it ticks much more and louder. When the car is running it seems to be inconsistent though. I did replace one of my cams , took out the one that came with the head I bought, and put back my stock one. I don’t think that is the source, but it could be. Maybe timing is off too.

 

[RubyEclipse]

alrighty, last video im going to be able to post with this noise. To afraid to mark things worse so im not going to push it anymore. It already seems to be worse than it was. Going to really see if I can narrow down the noise today.

Ok so today I dropped the oil pan, can see the crank and fly wheel clearly. Well well well, the sound got louder. Still narrowing it down completely. But I am looking at my fly wheel, since my clutch pedal started acting up in the first place too, I beg thags where my problem lies. I think I might have to drop my transmission here soon. The rods feel great, and don’t even kind of feel like they’re moving around. All nice and tight. What do you guys think i should do to confirm it being the transmission, or just dropping it right now.

Flywheel supposed to move like this? And when I turn the crank it makes the exact same noise, so i think we found our problem. What does this mean though? And do I have to move the trans?i think I’ll drop it from the bottom instead of pulling out the whole engine. let me know what you guys think, thank you!

nope - loose that is. Drop the trans you must.

Gosh dang it. this sucks, I won’t lie. How does that happen? Also is it okay to put my other “new” turbo back on? Or do i have to modify the ECU and stuff, my set up with the intercooler is now made for that, so the piping I made for the stock turbo fits really weirdly.

 

[pauleyman]

What torque spec did you use for the flywheel bolts?

 

[RubyEclipse]

Is this what crankwalk is? And perhaps did I do something wrong when torquing it all down? What do I check first to make sure I can fix this issue?

I was handed a paper from the guys who rebuilt my head and surfaced my block, he said this is exactly how they would rebuild the car. Had all the torque specs and everything on there. So I just followed what they had, I’m guessing it’s around 94 ft lbs like what I’ve seen everywhere else. If one bolt came loose legs say, what would the whole plate rotate side to side?

No the flywheel should not rotate independently of the crank. Push/pull on the harmonic balancer axially. See if the crank moves.

I tried with my hands and the prybar, just little bits, got nothing. I do hope me running the car with the plate like that didn’t ruin anything else.

Okay so it does have play, it’s not much, like at all. But there is some. I am able to hear a clicking when I push and pull. It seems very very very small amounts, but it does move.

It will have a little bitty teeny weenie bit of axial movement, it is just the thrust surface space which is in the thousands of measurement.
The REAL ISSUE was , that spinning chainsaw under your legs was fkn LOOSE. If it came loose, it would saw right through the floorboards and into whatever else is in its way.
Double, triple check the torque on the bolts and go around them several times.
You are very lucky that you were diligent enough to find the source. Good job before everything went to hell in a handbasket.
I would, at the least, use Orange Locktite on those bolts, so you're safe.

This had me cracking up I wont lie. I have pulled the axles out, going to take off the panel across and whatever else needed to drop it. It is going to be really hard to put this thing back isn’t it…?
