Loud rotating sound when clutch is depressed
Discussion
Just had the clutch replaced on my 996.
After the first clutch replacement last week my specialist reported a rotating noise after the clutch was depressed for 2-3 seconds. He and some other technicians agreed it could only be the release bearing so they replaced the clutch again including the release bearing.
After it's second clutch and new release bearing it's still making that rotating sound when the clutch is depressed as well as when pulling away in 1st or reverse gear.
Any ideas as to what else it could be? It's really stumped technicians and I'm at my wits end about it
Cheers in advance

""it's still making that rotating sound when the clutch is depressed as well as when pulling away in 1st or reverse gear.""
A faulty release bearing would creat that noise every time the clutch pedal is pressed, unlikely to affect just First and Reverse !!
""After it's second clutch and new release bearing it's still making that rotating sound""
It has been known for new parts to be faulty straight out of the box, Could it be that a bad BATCH has been sold as opposed to just ONE bad part ?
A complete assessment of the Flywheel, Forks, Pivots etc would be a good step moving forwards.

On my 996 if one pushed pedal down to the floor it was fine, but just a little further down and one would feel a slight vibration through the pedal and hear some rumbling noise.
On yours, the sound comes in 2-3 seconds after depressing the pedel. Does the sound then persist until pedal is released? If you then slightly accelerate the engine does the sound change?
You comment this happens in 1st/Reverse, but what about neutral?
My guess is ... fork is pushing the bearing and hence the spring plate too far forward and into the centre of the clutch disc. When in gear, the clutch disc is stationary and the spring plate is rotating against it. In neutral the clutch disc is free to turn, so no noise.
Definitely the correct clutch kit for your 996?
I assume new pressure plate too.
The clutch on my 996 was a pig to get right. Two well respected indies struggled, but we got there in the end. Main problem was peddle was slow to return. Lots of parts changed!!!

Yeah it happens in neutral.
it persists after 2-3 seconds until the clutch pedal is released and the same sound can be heard when moving off in 1st or reversing.
It's had it's second clutch kit and the specialist is well respected so it's really stumped them!
