Keep an eye on the level. Chances are the csc seal is starting to leak.

I have my original still. It's in my garage closet.

Failed twice at 6K and 59K so I am on my 3rd. Master cylinder --- I'm on my 2nd. Now I have the Tilton racing slave. So far so good. Feels slightly firmer than stock. Engagement is just right - not on the top or high.

Axmea?
 

If that is your white car, I'm jealous. People at work thought I was nuts to buy a second Z after the trouble I had with my 09 and the csc going out 3 times and the dealer not fixing it. I tell them the CSC is but one part, not the whole car and I can't get this driving experience and package in any other car at near the price. Several posters have recommended changing the master cylinder with the CSC. I plan to buy the after market CSC and replace the factory one at 36K when the warranty expires. I was thinking of replacing everything at the same time. Not sure if I should go with a different clutch either as some have recommended. Mine is street driven, not raced. I would climb over Porsche 911s just to get a good look at your car...

I didn't bother to replace the clutch when I replaced my working CSC with the Z1 kit at 51K miles; I shouldn't have any trouble getting another 50K out of it. Unless you plan to do more than drive on the street or don't know how to drive a MT, there will be absolutely no reason to replace the clutch at 36K miles.

Thanks for the reply. Whew, that is a big relief to read. So far so good with the white beauty I have. I was out of a Z for 11 months and man its good to be back. Really good news here.

My 2011 got to almost 40k (car totaled) and it was going strong.
My 2013 is at 24k and I'll be changing it out next week with a new clutch and flywheel, but the stocker is fine at the moment.

Changing fluid often is probably the best way to avoid damaging the CSC seals. At least every 2-3 years. In fact, same time brake fluid is flushed is probably the best.

21K and no issues so far (g37).

I do it 1-2 times per year :tiphat:

Same with brake fluid. I can gravity bleed the clutch without a helper, and I have a power bleeder for my brakes. Super easy and <$50 in fluid for both each change. No reason not to do it.

Failed at 51000 miles
 

2010 Nismo. 51000 miles at CSC failure. Installing Z1 CSC elimination kit and RBM CMC. Installing new clutch. Reusing flywheel.

I upgraded mine (z1 elimination kit) at 5yrs 36k miles, was proactive not due to failure.

2014 with 20k miles so far on the OEM CSC. Running an RJM pedal set up to minimize over travel. Oil cooler and fully insulated clutch hydro lines help keep clutch fluid cooler. Original fluid is still pristine.

changed the the GTR brake fluid @ 28k mi. and haven't had a problem since...a little over 41K now

2014 with 28.5k miles. I'll probably do the csc delete in the nearish future. I plan to flush all of my fluids except the coolant at 30k.

62k just switched it out

What does CSC and CSM stand for?
