I guess ill start from the top. About 2 months ago I purchased a 92 VR4 off of this forum and have since installed a spec stage II clutch along with the spec aluminum flywheel. The clutch installation was kinda tricky but me and my brother were able to take it slow and over the course of two weekends we had it up and running!
Well everything was great with the car, shifting smoothly, no slipping clutch or anything….well that lasted for about 3 weeks or so. In this time I put close to 1000 miles on the car driving home and what not. Anyways I noticed one day that the point at which the clutch would engage was getting closer and closer to the floor…I barley got it back home.
Since this time ive done much research and replaced slave cylinder along with installing a steel braded line and bled the system. Inspection of the master cylinder reveled that it was not leaking at all inside of the cab. I also adjusted the clutch petal (the extreme out position )in order to get it to grab in the correct location. After all of this was said and done I got it to work once again…for a day or so of driving. And once again last night I had to drive it home in second gear.
I went out this morning and the fluid level was correct so I decided to adjust the petal again and this time went as far out in one direction as possible. The allowed me to move the car around without notchy shifting but I really doubt it will last due to it engaging like maybe 1/8 of the way off the floor board. I also tested to see if the clutch was dragging once i was able to move it this morning and i was. Around 6500 rmp's it would start to creep forward. So I am kind of stuck….
-Is the clutch disc warped (I was able to drive it perfectly for 1000 miles before it went down)
-Could the master cylinder be bad even though it isn’t leaking?
-Or am I being stupid and totally missing something?
Thanks for any impute you guys have! It really sucks when the car is down but it’s so worth it once it’s up and running!
P.S. Sorry for the short essay
UPDATE....3/18 I intalled the new mater cylinder today and still no go!!! I bled a good two reservoirs worth of fluid out of the system and the clutch felt really firm…but when I started it nothing and it also lost some of its resistance. I even tried adjusting the clutch pedal in the two extreme positions and still nothing. Someone has to have some idea…once again im stuck…
-Furthermore does anyone know the 'throw distance' is on the arm that connects to the throw out baring (the distance the slave piston travels)? It seems to me that its moving the complete distance…which is making me think its something in the physical clutch…not cool…
-Update 3/20 I spoke to a mechanic I know and he printed me off the official way to bleed and assess the clutch hydraulic system. Im going to try this today and if doesn’t work ill be tearing the transmission out mon. If anyone has other ideas pleas let me know!
