Default Clutch Noise

So I only heard this this morning when I fired it up. Hoping to gain a bit of insight here as to whats happening.
With the clutch fully depressed to the floor, its making an almost grinding sound. At the very least Id say its more like a rubbing sound. The sound only happens in the last 1" or so of stroke till its fully depressed. Other than that its fine.

Heres a link to the sound...

Car has 110k km. Just had motor oil and trans fluid changed last week. Is my clutch getting ready to go kaput? Take it to my indie asap? Drive it?


Thanks

Copy that on the TO bearing.

Whether the fix is easy or not depends on whether you consider removing the transmission is easy. It's kind of a fun job, not crazy difficult, but you have to be committed.

It definitely needs to come apart if and when you decide to fix it, and that's the point here. You wouldn't go in *just* for a noisy-ish throwout bearing.

It probably won't fail catastrophically, and even if it does it wont do a lot of damage - but it will strand you.

The other thing to consider is that when you go in, you will absolutely want to replace the clutch and maybe the flywheel, and probably the AOS, and the clutch slave....the time to do it is while you're in there. Figure on $3K at least depending a lot on if the flywheel is replaced.

Just a few months ago my clutch went from feeling fine with no noises to a failed spring plate in one afternoon. That was at 190K kilometres, but since the motor was replaced by the PO at 70K kilometres, I am assuming that a new clutch was installed then also, so the clutch had 120K kilometres on it.

I don't abuse clutches, so if you ask me a failure around 110K kilometres shouldn't be a surprise.

I'd say don't panic just yet - drive it over to the indy if the noise gets a little worse, or right away if you just want to make it right. You'll be spending the money soon anyway.

Haha - totally not. Of course while you're in there you can replace that too!

In fact when my clutch failed that's exactly what I told my passenger - "hey great news - my clutch just failed!" I think I named the thread which follows my project the same also.


BUT - it was not to be for me. Turns out that the reman engine installed in my car in 2005 was a M97 not an M96 - and these have a different IMS design which can not be upgraded from the outside. This was Porsche's answer to the problem which they by then were fully aware of.

My IMS and RMS were bone dry - I left them as they were.

Good luck to ya ! Remember - if you have a problem that can be solved with money then you don't have a problem.

I had the very same issue in my '02 C4 Cab....got in there and did the throw out, clutch, pressure plate, flywheel and RMS - IMS was in good condition, actually had the pan checked and the oil filter for filings and no issues per my Indy.

My car did the exact same thing about a month and a half ago while sitting in traffic on my way home from work, it went from silent to sounding like a supercharger spooling up whenever I pushed in the clutch. I parked the car after that to weigh my options for how to deal with it. After about a week or so I needed to move the car around the driveway so I started it up and the noise was gone. Been driving it ever since and hasn't made a sound. Go figure.
