bout a year ago had master and slave replaced, two weeks after clutch started slipping. few months later had new clutch kit put it so it was fine, month after that started slipping again! car sat for four months so a month ago put a nother clutch kit in and new fly wheel, car runs good till it gets hot then starts slipping again, my only assumption is that something is boiling my fluid but i cant see anywhere that would be happening, please help

 

Is the fluid level low in the master cylinder reservoir?

 

No the fluids are fine

 

Sounds strange. I haven't had to troubleshoot problems with mine, so I have no firsthand experience in diagnosing clutch problems.

Did you replace the throwout bearing?

See if the release fork returns back to normal position (cold position) once the car is hot. Slave cylinder could be sticking too.

I had a slave cylinder go bad maybe two years after I bought it, but it leaked fluid and was pretty obvious. Don't assume that your new master/slave are working properly.

 

Get the 96 shop manual (look in the DIY section).
Adjust the pedal height by the book.

Here's what it MIGHT be...
Just when the clutch pedal is up at the top of it's travel, a vent opens up in the master cylinder, allowing the fluid pressure to release completely. Your pedal or the push-rod to the MC, might be adjusted too long. That vent never opens, so the fluid is trapped. As it heats up & expands, it partly disengages the clutch. That's when it starts slipping.

Another test...
When the clutch is engaged (= NOT pressing on the pedal) you should be able to push the throw-out lever towards the slave cylinder. If you can compress the slave piston into the cylinder, that means this vent is open like it's supposed to be.

 

slave nor master are leaking so the pedal is what I'm stuck with... Hopefully it will fix it.. My neighbors got a manual so I'm gonna try
