When I was at IPD last I think I was told that the clutch is rated for around 70 thousand miles. But that all depends on they type of driving you do and how you use the clutch. Mine has around 30 thousand and it was within a millimeter of a brand new one.
If the clutch plate was worn, and the pressure plate springs were fatigued I could not see that causing the slave cylinder to over extend. I would think it was a bent, broken or worn fork. I could not tell but I am wondering if the spring and point behind the fork is adjustable.
My problem is that I have not changed anything, so why would the cylinder be over extending. Btw, the last time that I replaced the cylinder it was because the fork had broke while driving. The last fork had gone about 200 thousand miles.
My old slave cylinder is being shipped to me right now. I am hoping I don't blow this one out. Which brings me to another question: I was reading through a shop manual that showed how to rebuild a slave cylinder. So, unless the cylinder is jammed, it should still be good right?
Hopefully I will figure something out by tomorrow, as I will be under the car praying for a miracle!!
Thanks!
