We didnt change the pilot bearing so maybe thats it. I know we changed the throw out cause Ive seen my stock one laying around the garage since.

Not properly broken in is what my first thought was. My problem with the pilot bearing is that it should make noise anytime the engine and the input shaft are moving at different speeds. Like anytime the clutch pedal is pushed

Nate

Yeah we know its not that. Youve heard how it only happens during engagement in 1st. I guess maybe the way it was broken in could have something to do with it. Its just wierd that after close to 20k miles it started doing this. Im not pulling the tranny anytime soon so I guess I'll just live with it and hope it eventually goes away. Until then I'll just deal with the wierd looks from bystanders.

I used to have a 4 puck unsprung clutch in my fatty prelude. And it would either chatter the whole front of the car, or shriek/squeal like I just ran over a puppy. There was no smooth take-off's

It'd only do it in 1st gear or reverse. That clutch never got broken in, just went str8 into ricer mode (bangin gears and doing burnouts in a stock car)

I believe because it was a puck'd and unsprung clutch disk that never saw any kind of break-in period, that since it was "attempting" to slip during take off's, the friction surfaces made noise trying to catch each other.
There's no problem with my trans other than it having almost twice as many miles as my motor. No grinds, no kick-outs...

On a side not, when that clutch gave out it sounded like rod knock.... It was still driveable (barely)....but it sounded like a rod was gonna come out of the block. Changed the clutch and the "knock" disappeared

buddy has the same thing in his LS/VTEC 6 puck un sprung

Nate

So Im going to conclude that this must be some kind of an unsprung clutch issue and theres really nothing to worry about. The thing still seems to hold great so I guess its just the surfaces trying to catch each other like marcj said that are making the shrieking sound. Man is it ever loud and annoying though.

You can combat this problem with an open downpipe.

You know you want to.

Yeah, had a ACT 6 puck unsprung in my old DA with clutchmasters flywheel and it made a school-bus like "WHERRRR" in first gear.

Nate

lol I know all about open down pipes. I made the 3+ hour drive home from school with an open header n/a and another couple times with about 2 feet of an open downpipe. With a b16 tranny revving close to 5k on the highway and no a/c driving with the windows down for that long I thought I was going to have permanent hearing damage by the time I got home. My days of open downpipe are over.

I have the same thing, 6 puck unsprung and it makes the same sounds.
