Made a vid of my "flywheel noise" , is it the flywheel? ---
There is a description in the video area for more info on my car and the issue.
I was thinking this was the dual mass flywheel making noise. Its a timed cam car and I heard they are even noisier than usual. Its louder near the end of the vid. I only hear it when the car is warm and at idle. 1990 LPE Topend ZR-1 with 43k miles. THANKS!!! --- http://www.youtube.com/watch?v=ja1Kq...ature=youtu.be EDIT: 2nd vid. -------------------------------------------------------------------------------- I took a new vid of the flywheel from the passenger side after my trip to the track. I can almost picture the weights bottoming out. : http://www.youtube.com/watch?v=jaGDqqvrMjY

Are u sure you're not thinking about single mass flywheel?

Does it go away when you push your clutch peddle in?

Do you have headers and is the Air Pump plumbing still in place?

If it goes away when you press the clutch in then it's possibly the pilot bearing at the tip of the input shaft to the ZF6.

As far as I know its the stock clutch and flywheel.
The last owner said he didn't replace anything, and there is no info on the Lingenfelter receipt for a clutch/flywheel swap. There are Watson headers on there, and a spot on the drivers side welded up. Where should I look to see if the Air Pump is still in place? I don't think it goes away when I press the clutch in ... I will be driving it again in a few minutes and will check for that. THANKS  ---

My Watson headers have fittings on the primary tubes that plumb together and pipe over to the air pump, which I think was in the drivers' headlight area. I took that out a long time ago so I can only dimly recall.
The one time I got what I now think was a flywheel noise it was hella louder than that. You may have an exhaust leak. Could be the air system. Good luck, - Jeff

In person I think the noise sounds SO much louder, but when I heard it on the video I was surprised how quiet it was.
I just took a drive, it does NOT go away with the clutch depressed. It is silky quiet and smooth on cold startup ... sound starts up immediately on a 2nd start/warm start. ---

Do you have original injectors?

My next thought is that it either does have a single mass flywheel or a bad lifter. I'm leaning more to a single mass flywheel because they tend to get louder as the car warms up.
