Steve, I’m almost certain the noise mine is making is the throw out bearing, my clutch master cylinder decided to start leaking today too. I’m going to replace both slave and master and see what happens. I put about 50 miles on mine yesterday/today and everything seems to be good to go. The weird thing about mine is this throw out bearing was in mine with the first install and it wasn’t making this noise. The noise comes and goes intermittently but i’m pretty sure it is in the clutch not the trans on mine. I fixed all my exhaust leaks too so I know that isn’t my problem this time around.
