Have a quick question on my clutch pedal. When my clutch pedal is engaged all the way I hear a loud chatter clunking type noise. if I let the clutch out just a little it goes away and I can still drive and shift with no problem. It only makes the sound when it is fully pressed, at idle or while driving. I was doing some searching and came to the conclusion that my clutch fork bolt may have backed out and my fork may be loose. Just wanted to see if that seems like something it might be to you guys. Any info would be appreciated.

Its the throwout bearing making that noise I believe. My old car did it. It was annoying but never gave me problems.

Its really weird I went out and drove my car this morning and it wasnt doing it anymore. Just went outside and started it up and its making the noise again. Anyone ever had this problem?

Yeah it was exactly the same way with mine. Sometimes it makes noise and sometimes it doesnt. It wont go away though.

Did you ever find out the cause of it?

I might be having the same problem at the moment. Check the thread out: https://ls1tech.com/forums/manual-tr...g-syncros.html Third post down is a link to a video, let me know if it sounds the same as what you are dealing with.

yeah it sounds like that but without the rubbing sound. Just the clank. I really dont want to have to drop the tranny, but that might be the only way. Did you ever find out the cause of the noise?

I'm not sure, I'm trying to pull my transmission today. People in my thread think its the throw out bearing, I hope they are right.

I never found out but Im 99% sure it was the throwout bearing. It did it ever since I installed my Spec stage 2 clutch and I drove it like that for about 3 years and sold it that way. I cant remeber if I replaced the throwout bearing or not. You will either have to drop the tranny or just live with it. I felt it was alot of work for one bearing so I just dealt with it.

My car does it and the Clutch/PP/flywheel/TO bearing are all brand new it is the noisy pilot bushing. My old 92 M5 Firebird did it as well

FWIW : I used to have a weird whining possibly grinding when I would shift into second. Sounded a little like that video. I changed out the fluid to check for metal and found nothing. replaced it with synthetic (redline) which didn't seem to do much immediately but, within a week or two it just went away and never had problems again. Definitely a PFM cure (pure f***ing magic). I believe my issue was definitely something with 2nd gear in the tranny though because nothing else had any problems. Otherwise, I just have the standard throwout bearing chatter when I'm in neutral with my foot off the clutch pedal. I wish there was a way to shut that chatter up when sitting still in nuetral. hehe...

Yeah its really weird. Maybe I'll just have to learn to live with it. But I cant imagine it being a natural thing. Something has to be wrong (with mine) just sounds to bad to be normal.
