• brand new OEM clutch slave cylinder installed 2 weeks ago, properly bled (problem existed BEFORE i replaced the slave cylinder)
• OEM clutch master cylinder (not sure of age, looks new)

• ive adjuted the clutch pedal engagement to a variety of distances, problem still occurs

• my clutch pedals tension/retainer spring clasp is busted. meaning the spring at the top of the clutch pedal assembly no longer tensions the pedal. i have to replace the entire pedal to remedy this (which i plan on doing in january of 2012)

• ive noticed a very faint metal spinning noise coming from my tranny tunnel as i engage the clutch via the pedal at a complete stop. ive never really noticed it before, but i never really listened for it before.

• my clutch chatter seems to be sporadic instead of a normal thing (which is odd)

• the car is used for DAILY DRIVING ONLY. nothing ive installed on the car has seen ANY track abuse whatsoever. my SR is fairly bone stock outside of a few odd bolt ons. nothing making huge power. turbo is still pushing stock boost. again, its a daily driver, not a track car.
Ok, answer this, if your slowing down out of gear, does the car almost stall?

Yes? then it has to do with something other than gearing..

No? proceed

when sitting at a dead stop, can you push the clutch in, and easily go from one gear to another with the engine running?

if you hold the clutch pedal down while in gear, does it scoot forward, and stumble?

does the clutch pedal feel loose? as far as there isnt constant clutch spring tension on the throw out bearing? this could be the throw out bearing pivot arm bolt.. i had that break on me once, and it was an "awesome" experience while driving around..



give us some more info on exactly whats going on, when the problem started, what were you doing before the problem happend.

help us help you.. although this is Zilvia, and asking for any help will immediately get you bombarded with "NOOB" "DIE" "Search fag".

1) Slowing down with the car out of gear is fine. no issues there whatsoever.

1A) No (moving on)

1B) No (moving on)

2) yes

3) no

4) clutch pedal is feeling slightly mushier than usual (could just be me though)

5) already have a NISMO pivot ball unit installed

i think ive already covered the rest of your questions in my original post. the car is daily driven. it does not get beaten on and has never been tracked since ive owned it (over a year now). the tranny is perfect, no bad synchros at all (no grinding between gears). gear oil is 80w-120 and was changed in december when the clutch was installed. i know for a fact its not a gear oil issue as ive run 80w-120 in all my 240s since 2002.

the reason i added the recirculation thing is because im sure someone would say "oh its because youre venting your BOV, better recirc it blar blar blar"...didnt want to have to arm the flamethrower.
