What is Up with These Clutches!?

Spooler · 11-04-2014, 06:38 PM

LOL, my wonderful clutch is rattling and making noise when the clutch is depressed. I feel it in the clutch pedal also. I want to take it in to the dealer (old friends) but I don't want just more of the same. I most definitely won't put up with any "it's not under warranty crap". My CSC is still good at the moment but it is only a matter of time. I loath this sorry design.

this is unfortunately a clutch issue and you can't get rid of it, unless something is broken and you have your own unique problem.

the factory fireshield over a section of the clutch line near the bell housing is inadequate. it is possible to develop similar symptoms with just normal street driving because of the proximity of the clutch line to the cat.

You did mention that you get the same symptoms after cruising on the motorways which seems odd because the airflow would keep things tame.
With the warm ambients and traffic here in Sydney, i resorted to replacing the fluid with RBF600 and wrapping almost all of the clutch line near the cat with exhaust wrap (both the hard line and the flexible section), all the way to the bell housing.

That cured the issue and i feared the traffic no more. This was before i had the CSC replaced due to fluid loss. I think the dealer removed most of the wrap when they replaced the CSC but i havent really noticed the mushy pedal issue since the replacement. Fluid level is unchanged, colour is perfect. I'm happy enough even thouggh the clutch feels a bit too on/off for me. as in the friction point is very narrow, but im not going to disturb anythinf until it really goes south. good luck!

I noticed on/off feeling you mention when I did a flush months ago to recover from an un-drivable situation. The flush made all the difference. I also looked at the heat wrap option. It's interesting to hear that wrapping the tube solved your problem. It's pretty clear that it was in fact heat related. Did you have another OEM unit installed?

UPDATE:

Dropped my Z off this morning at the dealer. Just got a call stating that they noticed insufficient heat shielding on the clutch line and damage to the heat shielding around the CAT.
They flushed the clutch fluid, which was completely blackened, checked the system for leaks (none were found), addressed the clutch line shielding, and are replacing the CAT under emissions components warranty.
I get my car back this afternoon. We'll see how it feels. $0 charge for services.

It seems that the last time the CSC was replaced, it was not buttoned up correctly which over time led to the problems.

Who knows. I am already looking to get the zspeed unit because, YES, I know this will fail again at some point... I have a 3rd party warranty with a $100 deductible that I used to get the first CSC replaced. I asked the dealer if they would install the zspeed unit instead of the OEM unit WHEN my current unit fails if I supplied it.
They didn't think it would be a problem, but they would have to document to the warranty company that a non OEM part was installed, which may void any further warranty service on that part.

...That's fine by me.

I will just make sure they replace the master too.

If they have a problem installing a non OEM part at the dealer, they said I can have the work done at another shop that accepts warranty claims.

Hopefully that won't be for a while yet.
