06 6mt coupe. 56k miles. I have been searching here and 6mt for hours now with no threads that have the same issue I am having. When I start the car up in the morning, clutch is great no noise or anything. After it reaches operating temperature and is driven for 30 mins or less, the clutch begins to make noise when releasing. It sounds like the creaking of an opening door. This sounds like it is coming from outside the car. I know our transmission and clutch assemblies are some of the loudest out there but this just recently was noticed. The clutch still grabs great and doesn't slip. I have also noticed that when idling and in neutral if I push the clutch in and dump it the RPMs will shudder for a fraction of a second on dump. I have included a link to my YouTube video showing the issue.

I should also add that it sounds like it's coming more from the driver's side of the car. Nobody has any input on this? I know you techy's are out there, cmon start that hamster on the wheel in your skull and help me out here. I'd rather not take it to the dealer as I am only in powertrain now, b2b is expired.

 

Well after some research I decided to try two cheap possible solutions. So I had some time this weekend. Lubed that pivot point near the slave with copper grease and a paint brush as well as white lithium spray. Also bled the system with fresh dot 4 fluid. Noise and gummy pedal still there when car heats up.*

Funny situation this morning. Had been doing some city driving and clutch was creaking on slow release as described in first post. Pedal also got noticeably harder to depress. Hit a bridge and some asshat in a bimmer wanted to play. I dropped it into fourth and obliged. Got it up to around 130 before we ran out of road then just cruised after. Got back into traffic and clutch was like butter with no creaks or squeaks. Wtf gives?
