This CSC issue everyone talks about....
 

How bad is it? Are they failing on everyone's manual cars or only those who hammer the snot out of them?

Dropping the trans is no small job and I don't have the facilities to do it. I've got under 30k on my car and I don't beat on it...mostly just used for DD type duty. It's a 2014 base model. Paying $1500+ for something that's not broken bothers me.

That said I assume it's an easy swap if you have the trans out for a clutch replacement, yes?

The stock CSC WILL fail. It's just a poor design so expect it to fail even if you're not beating on the car. Best option is once it fails to replace it with the ZSpeed CMAK kit in order to convert it to an external slave cylinder.

And yes if you already have the trans out for a clutch job, you'd probably want to replace the CSC.

I've put 65k on my 2010 Z. No issue. Could it detonate tomorrow? Sure, but I'm hoping it doesn't, lol. Had I replaced with the csc delete or hd csc years ago when I bought my Z, I'd have blown $1400 on preventative maintenance that so far hasn't been necessary. At least when mine goes the car will be due for a fresh clutch anyway so it won't be much of a loss. I've kept up with my fluids though. Not sure if that makes any difference in the csc life. Also, I don't exactly baby my car, but I don't take it to the strip either. I usually drive it in a spirited fashion until I get tired of smiling.

When I replaced my clutch I replaced my csc with a zspeed heavy duty and my master cyl at the same time. How bad is it when it fails? Not that bad, it’s just like you don’t have a clutch... at all.

I have 36,000 miles on my Z. And yes, I beat on it. Still have the OEM set-up. Had no issues yet. Have the clutch line wrapped with insulation down by the exhaust pipe to keep the heat away. And replaced the stock fluid with Motul 600 brake fluid. I'm not counting on it to last. So my next winter project with be a Tilton lightweight 5.5 lb clutch/pressure plate, flywheel, with the CMAK, RJM pedal and a Tilton master cylinder. Changing the shifter from a TWM to a Coolerworx.

If it's your DD and you have backup transportation, I'd wait until it starts acting up. Some ppl have had good luck - you might be one of the lucky ones.

I just keep the fluid clean. 60 or 70k, many hard launches,many many hard miles in the mountains still ticking. I'm running it until it or the clutch goes then its upgrade time

I have driven a 2012 Nismo to 60k miles and my 2013 Nismo to 78k miles with no issues. Just keep the fluid clean. I would drain and fill mine ever other oil change.

What are you using to bleed it? I wanted to use my Motive bleeder but haven't found a cap for it.

What’s wrong with the TWM? I’m a fan of mine

Check this post out and you’ll see.

Gravity baby.... The fluid moves so fast out of it you don't need a bleeder. Just don't goof up and let the master cylinder run dry. Always keep some fluid at the bottom of the reservoir. Once I get it the fluid down to the bottom I wipe clean and re-fill and do it again. You'll see the fluid start to come out good and clean at the CSC.

Try something different.

I'll give that a shot when I get home. Thanks!

Before you do it. Take a syringe to suck out the reservoir. Then use a paper towel it wipe it clean. Be surprise at the junk on the towel after you it do. Then refill with fresh fluid. Now do your flush. ;)

OP, I also have the oem stock setup and also started a thread about this, as I got paranoid before. I’ve gotten mixed responses and I just stopped worrying about it. I have a ‘13 with approx 33k miles, and do both light and spirited driving, and no issues. I also had an ‘07 350Z which apparently also were prone to the same csc clutch issue, but mine didn’t (bought her with 16k miles and traded at 81k miles).

It's on you. Lady luck is fickle. Sometimes she loves me sometimes she doesn't. The thing with Lady Luck is that if you prepare for her tantrums, they aren't bad. Basically, get it swapped now. I have the Z1 CSC deletion kit, needs adjusting, the Zspeed one does not.

A properly designed system needs no adjustment. The problem with the Z1 kit is it always needs adjusting.

The steering wheel lock, fuel starve, and the CSC problems don't effect everyone. There is no rhyme or reason as for who get's it, or not. :shakes head: It's all random. :shakes head:

With the Genuine Nissan CSC issue it’s more of a question of when the Genuine Nissan CSC will fail. I am the record holder here I have replaced four Genuine Nissan CSC’s before finally installing the Z Speed Performance CMAK Kit and I am happy I did. Clutch and flywheel replacement will get expensive over time. Also over time the fluid can make it’s way into the cabin of your Z ruining your interior carpet. I hope you have AAA or a towing service to help you when your Z is left stranded in the middle of no where from the dreaded CSC failure good luck.

Leave it to Nissan to never fix something over a decade.....:shakes head:

how much time does it take to empty the clutch fluid reservoir?

do you need to initiate it by pumping the clutch pedal or just loosen the drain valve and let the fluid out?

Loosen the bleeder.

I bought my 2015 370Z Sport new and drove it like I stole it since day one. I'm already into my mid-forties and the foot is just as heavy as when I was in my teens and twenties.

The sweet scent of clutch fluid began permeating into the cabin at about 2 years into ownership. I began having to replenish the clutch master cylinder reservoir frequently at around 25k miles (3 years into ownership).

I converted (before complete CSC failure) over to the CMAK system and replaced the whole clutch assembly with a Z-Speed Performance Stage 2 Clutch Kit at 28k miles. No auto shop in town wanted to perform the conversion (citing liability issues)...so I ended up doing the work myself in 4 phases.

I currently have around 2.5k miles experience with this setup and absolutely love it.

For some reason Z1 was all that was running through my head when I got it done. Zspeed, I was reading around, that some had leaking issues with it, then I found out Z1 has had failures as well.

You live and you learn. Regardless both are great, Z speed tops it due to the auto adjust.

Really? That's strange. . . You'd think some would be up for it and able.

Yup. I thought so too. They were only willing to replace the CSC with the OEM part. The risk was unacceptable.

52k miles so far on the original clutch and CSC, no issues so far *
