'99 996 clutch noise - should i be worried?

[tcleaver]

I'm a new owner of a '99 996 C2 looking for some advise as to my next step. My clutch pedal is extremely stiff and squeeky. I'm coming from a 2 year old VW Golf GTI 6-speed and driving the 911 with the stiff clutch is very different. The dealer said the previous owner installed a 'racing clutch' so i'm not sure if the symptoms I am seeing are normal or not. When i press the clutch lightly I get a rattle and when i press it all the way down i get a whinny shrill high pitched noise. The car makes some rattling noises when it starts although these seem to stop or at least become less apparent after 30 seconds or so. However this evening i noticed that when parked and running there is a rattle from the rear right of the car that stops for about 15 seconds and then starts again. I am thinking about taking it to the dealer on Monday and have them drop the transmission and check it along with the clutch, IMS and RMS. Does that make sense and is there anything else I should have them look at? FYI, they have already done a major maintenance service on the car which included changing the oil and filter. There was nothing in the oil or in the filter and there are no oil leaks. Any feedback would be appreciated. Thanks

Was there also a lightweight flywheel installed by the previous owner? If so, that might explain some of the rattling that you hear.

I have a one piece lightweight flywheel and the transmission rattles. I understand this to be backlash in the transmission. It occurs mostly at idle. When I press the clutch in it goes away since I am disconnecting the drive line from the transmission. I can faintly hear it to about 2000 rpm and then the transmission is loaded and no noise. This is common and "normal" for this set up. The whirl sounds like a throwout bearing to me but wiser gents like loren might be able to help further.

The rattle, I would not worry about. The other symptoms, I would have checked.
