High pitch clutch noise?

[The Hoth]

Is this some sort of built in warning mechanism to remind the driver to release the clutch pedal quicker?

It always happens when in the full stop situation, I release the clutch pedal and give some gas. You know, sometimes the right foot is faster than the left foot.

The sound comes from behind. A little high pitch. Like something is rubbing something else.

Is it normal?

:o

Sounds like a throw out bearing to me. Best have it checked out.

It doesn't happen all the time. It only happens when I am lazy with the clutch.

So this is not a built in warning mechanism huh.

Throw out bearing......Does it mean the engine has to be taken out for mechanic to check?

Typically the throwout bearing will make noise when the clutch is disengaged. (pedal in), not when engaged. Are you sure it is coming from the transmission and not the engine?

I am pretty sure it is from the transmission.

I can dulplicate the noise just by giving more gas and release the clutch pedal extra slow at the engagement point. It is like some metal part is rubbing some other metal parts.

It only happen in 1st gear at a full stop.

I would say, depends on how careless I am. It happens once every 100 times.

How many miles on the clutch? Throwout bearing would make noise whenever the pedal is depressed. Is there any noise if you put the car in nuetral and let the pedal in and out?

I have similar in my Boxster.

I have heard input shaft bearings that are going out do as you say! As you let out the clutch it puts a load on the input shaft.

23K (original clutch from the factory).

It doesn't happen every time I depress the pedal or release the pedal.

It only happens when I am lazy and giving too much gas at the clutch engagement point (N to 1st gear shift) while releasing the clutch pedal too slowly.

I remember in another manual car, I did the same thing. Especially, when I tried to unstuck the car by moving the car forward and backward. I would smell the clutch was afterward. Instead of being able to smell the clutch, I've got these high pitch noises from the P-car everytime I was too slow releasing the clutch (only at the N to 1st gear shift though, 2 to 3....5 to 6 are fine).

Interesting. B)

My car had the same problem. It was the throwout bearing. They removed the clutch and transmission, and replaced the clutch disc, throwout bearing, etc under warranty.

Hoorah for Porsche. I must say my old clutch NEVER felt as smooth as the new one. It is like driving a brand new car.

I thought it is a wear and tear item. What did you say or do to get them repair it under warranty? I'm curious. :huh:

Just curious if this problem was solved. There are many posts about clutch noise but this one matches my symptoms exactly. I have a 01 C2. which had a recent clutch change. (12000 km ago)

[perucho]

Mine started doing exactly the same today :huh: The car (03 C4S) has 73k miles so I'm just going to get a new clutch kit installed (or I may try to do it myself). Any thougths? Should I be looking at something else? Any input would be greatly appreciated. Thanks!
