Zod Posted August 26, 2014 Share Posted August 26, 2014 Guys, I called into a nissan dealer earlier this year to price a new bumper and while I was there I was informed that there were two recalls outstanding on my car, BCM and CSC replacement. I knew the gearbox had to come out and asked if I supplied a clutch and flywheel could they fit it, no problem they said. I booked the car in during February this year. I supplied a competition clutch stage 2 and flywheel and picked up the car later that day. The clutch was quite grabby and the whole car shook badly when trying to pull off but I knew about the 500 mile bedding in and expected it would get better. It still isn't comfortable to drive but got a bit more tolerable. Fast forward to May and the clutch pedal started the whole dropping to the floor lark. Shortly after this I started losing clutch fluid and left the car back to Nissan. I waited to hear if this would be covered under the job warranty, and of course, the aftermarket clutch and fly were blamed first. Nissan gave the go ahead to replace the CSC again as it was p!ss!ng fluid. Got the car back and all was well. Now in the last week I'm getting the same symptoms and today I noticed a clutch fluid drop. I'm going to assume CSC again as I can't see any signs that the master cylinder is leaking. My questions are: What causes the CSC to fail in these cases? Could the clutch and fly be a contributing factor? What comeback should I have with the Nissan garage are they obliged to replace this again? Any Help and advice appreciated! Quote Link to comment Share on other sites More sharing options...
Ebized Posted August 26, 2014 Share Posted August 26, 2014 If it were me I think I would seek specialist advice. Whilst it sounds as the Nissan Dealer you used has been helpful, maybe there is something they are doing, or have not spotted, that is causing the symptoms to return. If you post up where you are located (you can do this in your avatar profile) that will help with suggestions as to who to see for a second opinion.

GMballistic Posted August 26, 2014 Share Posted August 26, 2014 Fyi ~ some HR owners from what I've read have upgraded their CSC. Believe it is this one used in the below link. Link: https://www.conceptzperformance.com/Cart/description.php?II=4592 Could be a worthwhile investment by the sounds of it as the OEM one doesn't seem up to the job, ...unless it's something the Dealership are doing wrong each time.

Mark@Abbey m/s Posted August 26, 2014 Share Posted August 26, 2014 We have seen stock CSC fail with after market clutches. Normally the higher loading from the uprated covers cause issues. The issue with the CSC is it doesn't like heat or the extra load. Do you think you at ride the clutch a little? Mark 1 Quote Link to comment Share on other sites More sharing options...
marzman Posted August 26, 2014 Share Posted August 26, 2014 Look for posts by Greekman, if they're still on this site. If i remember rightly he had an HR and had no end of troubles with his CSC. Did ZMANALEX assist in his situation? Quote Link to comment Share on other sites More sharing options...
Zod Posted August 26, 2014 Author Share Posted August 26, 2014 If it were me I think I would seek specialist advice. I am based in Dublin and there are not that many Z specialists around! Fyi ~ some HR owners from what I've read have upgraded their CSC. Believe it is this one used in the below link. Link: https://www.conceptzperformance.com/Cart/description.php?II=4592 I've seen this and wondered if this completely sorts the issue, I'd happily pay the money not to have this issue again. I'm undecided whether to persist with Nissan or take the hit on the updated csc and drop the box myself. We have seen stock CSC fail with after market clutches. Normally the higher loading from the uprated covers cause issues. The issue with the CSC is it doesn't like heat or the extra load. Do you think you at ride the clutch a little? I bought the clutch and fly package with the understanding that it would be a direct replacement for the existing nissan gear. I don't ride the clutch at all and always use the footrest. I was even more careful pulling off after it failed the first time. Thanks for the input guys, looks like I may just bite the bullet and get the upgraded csc and install myself. I had planned on getting the box off to get the input shaft bearing done in the near future, so why not do the csc. Quote Link to comment Share on other sites More sharing options...
Ebized Posted August 26, 2014 Share Posted August 26, 2014 May be worth taking a look at this thread: http://www.350z-uk.com/topic/89264-nissan-clutches-are-crp/ 1 Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted August 26, 2014 Share Posted August 26, 2014 The combination of the uprated clutch and the OEM CSC will more than likely be your issue. Fit the uprated after market CSC kit and all should be well. Alex. 1 Quote Link to comment Share on other sites More sharing options...
Zod Posted August 26, 2014 Author Share Posted August 26, 2014 Appreciate the help guys, I'll put the car off the road for a while and order the upgrade. Are they available locally (UK) or only in the states? (Zspeed/conceptz) Quote Link to comment Share on other sites More sharing options...

HaydnH Posted August 29, 2014 Share Posted August 29, 2014 (edited) Hmmm... I don't think my car has had either the airbag or CSC recall work done, amazed I haven't heard of these issues before! I better get in touch with my brother. EDIT: Both have been previously sorted on my car. Edited August 29, 2014 by HaydnH Quote Link to comment Share on other sites More sharing options...
Zod Posted May 6, 2015 Author Share Posted May 6, 2015 Update I don't like dragging up old threads but I think it's worse when they're unresolved! I took the car off the road for winter and decided to take out the gearbox and have a look at the clutch and fly. It turned out that either the new pressure plate or flywheel was faulty/damaged with the result that the disc wasn't being clamped evenly causing the massive shaking when the clutch was engaged. This may have played a part in the multiple CSC failures I had in a short space of time. I have since installed an Xtreme clutch and fly with the uprated CSC and have to say it is absolutely fantastic! I am totally back in love with the car again and it drives great, even in stop start heavy traffic. Massive thanks to Ewen from Clarke Motorsport for supplying the kit, couldn't be happier! 1 Quote Link to comment Share on other sites More sharing options...
