My C2 Clutch Noise


Recommended Posts

hello, i am new to the forum and excited to get reading the thread to learn about these cars. I have a 2003 c2 all Speed Yellow B) . Today i went for a night drive and after 20 minutes of issue free driving, i noticed a noise when i depress the clutch. When changing gears and releasing the clutch the car makes a loud 'blow off valve' like noise. Like air is being released somewhere. I limped the car home and coming up the driveway the car made another loud whining noise while creeping up the drive. It is only when the clutch is engaged about 50% of its travel. What could this possibly be?

Sounds like it could be the throw out bearing may be going bad.

I though it might be but I for sure am not mechanically inclined when it comes to a porsche. Does this seem to happen instantly? It literally was showing no symptoms until one gear change and bang theres the noise. Also around how much is it to replace the tb?

Quick or intermittent onset is not unusual, because you are going to have to pull the trans to replace it, you may also want to look at the clutch while you are in there (rather than have to do it all over again in the near future if it is worn), and I would definitely recommend up dating the RMS and replacing the IMS rear bearing while you are in there for the same reason. I would also do the AOS at the same time as it is out in the open when the trans is out and a few min. to replace rather than a couple hours when the car is assembled. Cost is going to depend upon the shop's hourly rate, but a project like this is going to consume several hours of shop time, plus parts.
