OEM CSC over 60k miles?

nis350 · 08-31-2016, 10:37 PM

Just curious if anyone got more than 50 to 60k miles out of the OEM CSC? Mine went about mid 30k miles.

Spooler · 08-31-2016, 11:55 PM

Yes, I got over 60k miles on my 2012 Nismo before I got rear ended and the car got totaled. Another guy on here got over 120K miles on his before it went.

i just hit 40k on my 2011 Nismo without any problems. I'm starting to get a little worried though, ill probably switch to a CSC delete soon for preventative measures so i don't get stranded somewhere.

61k here, still working. I adjusted my peddle engagement lower. It might help but don't know.

Keep an eye on your fluid and change when needed. I am doing it every other oil change. It is quick an simple.

I got 51K miles out of my OEM CSC before I installed the Z1 CSC Elimination Kit. The original OEM CSC was still ok, but the master cylinder was starting fail yet again. I had already replaced the CMC twice by then, and I'm currently on my 5th one at 83K miles.

30K so far on my '14 Coupe and still OK.

nis350 · 09-02-2016, 01:31 AM

it is interesting that there is such a huge range in term of mileage between failures. I read some failed with less than 10k miles while other lasted 5 times longer in term of mileage.

I wonder if it has to do with 'how' the car is driven?

Ventruck · 09-02-2016, 01:51 AM

I swapped before it could fail on me. 30k miles on it, I took a look at it and I couldn't make out any stress cracks or anything. Then again I wasn't trying to get my hands dirty. Car on record had a fluid flush (previous owner), and an account of leakage into the transmission case. Could've actually been the master for all I know.

Production on the CSC is essentially inconsistent. Some owners will have theirs last, others claim failure upon test drives or right after purchases. If driving competence was to blame, I'd think those people with early failures would've also had bigger transmission issues to deal with. I do believe in favorable conditions, though. Weather, frequency of stop-and-go, flats vs. inclines, etc.

It has to be driving conditions. If you sit in stop and go traffic it must be an issue. Heat is no doubt what is causing the problem. I have to change my fluid every 8K miles because the fluid goes to crap. I use Motul RBF 600. I did on my previous car also. It would be interesting to get more data on peoples driving conditions, then we could point Nissan on how to test the CSC so they could duplicate the problem and come up with a solution. All we get on the board is a bunch of bitching.

I hear you. I read that some failed immediately after replacement. I assumed that was due to improper installation. My guess some of the key factors are heat and vibration that cause the rubber seals to fail???

Does the 350z or other Nissan models use the similar CSC and if they experienced early failures as well?

Yes, The 350z HR engine cars use the same setup. The earlier ones used the external CSC that Nissan has always used before.

nis350 · 09-04-2016, 07:10 PM

Agree that driving condition is probably the main cause. Dropping the clutch at high rpm and speed shifting would generate a lot more heat and vibration.

I imagine the fluid would be less of a factor under normal driving condition. The fluid should not deteriorate the rubber seals assuming they are compatible with the brake fluid.

59k and no issues on my previous Z before I sold it. 18k on my Z now and nothing yet.

Jimbo370 · 09-04-2016, 08:16 PM

I have 81k miles on my OEM clutch. bought the 2009 Z car at 52k. I can tell the clutch needs adjusting. I drive half city and half highway and use neutral a lot for what its worth.

don't jinx me
