harmonics at 2-3k?

[NickP]

What flywheel are you using?

[Spaz]

All in the driveway. last time was with me underneath it. This. Sucks.

What I can't understand is why it is only when it warms up. There is only the windage tray back there on that side of the pan right? I'll get a video today. Hoping it's something simple.

I can't imagine it making a difference but I used 15-40 dino oil when I changed the oil.

Are the headers hitting anything?

[etxxz]

i was gonna ask what engine and tranny mounts you're using...specially the tranny mounts. free standing r3ving or only when moving/coasting?

clearance of headers and front sway/subframe. booster. If its the engine itself. Good luck to you mr. anjos.. jr..

What flywheel are you using?

12 lb m20 flywheel from I forget what company. Bought it from here or e30tech. It was the guy that was selling m20 and m42 flywheels in the same thread, brand new.

Are the headers hitting anything?

I think they barely touch the sway, but that's not what is making the noise.

tranny mounts are e30 g260 mounts with custom brace. The brace is a little low and the mounts are actually streched instead of compressed, but it's not a tranny driveshaft issue. Car is in neutral in my driveway and noise is constant whether clutch is pressed or not. Will try to get a video of it asap.

sucky sucky. bb soon with a vid...

Go get a scope and try to find the noise I bet its coming threw the bellhousing.

These things do work believe it or not.

scope would blow my ears out. it's become that loud. Going to grab video now...

[MIKe30]

well, i take back the scope comment and my uncle will be bringing his mechanics scope home from work tomorrow. I can hear a bit of a rattle, I believe (hope) it's coming from the bellhousing. Part of the belief is the extreme vibration that seems like it's coming from the transmission.

here is a vid with sound. I have 3 more vids but it's late and I can't listen to them now. I did hear this one and I know it is the one that displays the sound the best. This was after the engine warmed up. When cold, it just a slight rattling/loose sound then when warm turns into this. Extremely hard to tell if it's from the rear of the block, or the bellhousing of the tranny. Best heard from underneath - where this vid is taken with a buddy's phone.



My dad believes it may be the pilot bearing. We used a puller to remove the old one, the new one was unusually easy to slide in. IIRC we barely even had to tap it, if at all, to slide it back into position.

Any thoughts?

That sounds like it could be one of the bearings in the trans, but they make more of a grinding noise when they go bad. If it doesn't go away with the clutch pedal in, then I would rule out the throw out bearing. It's a little high pitched though, I'd be worried about play in the input shaft.

You didn't see any leaks causing an insufficient amount of fluid did you?

[Spaz]

Since the noise doesn't go away when clutch pedal in, i'd blame the pilot bearing in a heart beat.

Only other thing i could think of would be an issue with the flywheel? Eitherway i'd be yanking the trans.

:( either way not a fun way to start up a swap...

I know how you feel though dude. My first swap, the head ended up being cracked in 3 places. That was a fun first start up...

Yea, no difference with clutch in or out.

yea, this is part of the reason why i'm so fucking $$$$ deep into this motor. I didn't want to have to worry about ANYTHING after getting it running, and now this. It will honestly be a relieft though if it is just the pilot bearing with no other damage to the motor.

Is it possible or likely to have any damage caused to the block by a pilot bearing that has slipped out of position?

[Spaz]

I doubt any damage would occur, what i'm picturing is the outside race of the pilot bearing spinning inside of the flywheel instead of staying still.

Reliablity Power Inexpensive

Pick 2.

I am 13k into mine. And I even had the S50 - Half the 5 Lug - and the brakes and suspension. The only problem I had was that my dipstick tube oring destroyed it self and my booster split in half.

When doing a major change you are always going to have little things to happen. For the most part the problems are still pretty small.

That sounds like a PCV is stuck. OBD 1 or 2 Manifold?

13 came and went a long time ago for me. OBD1 manifold. No pcv or air/oil seperator at the moment, which may be part of my vacuum issue I suppose.

I've said it before and I've said it again, noise is DEFINATELY coming from rear/bottom of block or right at start of bellhousing.

Just got a hold of my uncle's scope. Going to go check it out now...

[416stroker]

It soulds like a bearing to me. I just listend to your video.
