370z CSC Problem (2017 base 28xxx km)

Z34_JU

Hey thanks for the reply, i totally understand your pov. I was intentionally going to go with the CMAK kit from Zspeed, but they have gotten hit hard from Covid & their means of operation were slashed in half. The average wait time would have been 2-3 months & i need this done asap.

The reason why i immediately turned away from the Z1 kit is because i read somewhere you need to fine tune the kit as your clutch wears down over time. I couldn't really find any statements on here but i would like to ask your opinion being that you seem to know, is that true? & how?

I have the Z1 kit installed (for about 50K miles). Adjustments aren't bad. I maybe did them every oil change and they're easy to do. However, the kit is a piece of garbage. I've had the slave cylinder fail on me 3 times and Z1 only covered the cost once (every new cylinder I got was a new design because they kept having issues). Kinda annoying since my OEM CSC never failed and the Z1 slave gave me issues

I picked up the ZSpeed CMAK along with a clutch kit from Joe a while ago. Haven't installed them yet but I know I won't have any issues like I did with Z1. ZSpeed is apparently on point even during Covid, so not sure where you heard there were delays...

Got it, understandable now. Like you, I had 0 interest in fine-tuning the Z1 kit on any kind of basis. JAR mentions it above. 2-3 months is a pretty long wait, so it sounds like you're probably making the right decision as long as you're working with a good fabricator. Good luck to you sir!

I guess I got lucky. I ordered my clutch kit and CMAK about a month ago and it arrived in four days.

Can you please explain where you heard this from?
ZSpeed Performance has no issues with getting parts out the same day,

Hey Joe, wow okay then my local modshop blatantly lied to me or tried to bring business to their garage, thanks for the info, i will be in touch about purchasing.

Julian

JLarson

This probably should go without saying, but I'll say it anyway... if your mod shop was willing to lie about that, they will lie about other things. Pick a different shop.

They lied to you once. They will lie to you again. Tell them to

Already on that haha, stopped bringing business to an old garage that took advantage of me when i didnt know ****...anyways quick question to you and Rusty. Should i bother changing clutch fluid & bleeding clutch line prior to getting a date at a garage which is in 1 month plus? Maybe to extend the life of my current csc (doubt that will happen) but i also dont want to make the problem worse, car still engages gears and drives as we speak. Thanks.

Julian

JLarson

I'll respond for myself only, as Rusty is much more technically proficient. When I did my clutch, I had a lot of trouble bleeding the line, to the point where I had to pay someone else to do it for me (guy from Infiniti). Yes, if you can do it correctly, it'll probably extend the life of your CSC. If you can't, you won't be able to engage gears. I don't know your skill level, so weigh that for yourself.

In this case I would recommend a simple gravity bleed on the clutch. Ranger method the fluid in the reservoir and make sure it's topped off. Then open the bleed valve and let it drain. It will be slow. Let the reservoir drain until it is near the bottom (DO NOT LET IT EMPTY OR AIR WILL ENTER THE SYSTEM) and then close the bleed valve and top off the reservoir again. A single reservoir drain may not do the entire clutch system, but it will be close. Repeat the drain process again if you want to be sure.

If the seals are also going out in the master cylinder, it is my experience that pumping the clutch pedal makes the bleeding process more difficult and not easier like it should.

Sounds like you've already been having issues. So a clutch flush could definitely help reduce the risk of something happening in that time. But you'll probably be fine as well since we're just talking about a few weeks. I'm guessing that most people wouldn't bother and most of the people that would bother are DIYers in their own garage.
