I finally had my car back on the road and driving nice after nearly 2 months of downtime (had the trans gone through and replaced the broken 10 bolt rear).

I was just taking it for a spin after I had just put a new alternator on to get rid of the squeaky pulley on the old one (go figure, the squeak was still there anyway ) and about a mile from home I got on it in first gear, shifted to second, wound it up, then when I put the clutch pedal down it felt light and I couldn't get it out of second. So I started to limp it home in second (hey not too bad since I have 3.23s in it right now ). Just before I pulled in my driveway I tested the clutch again and some of the feel came back and I got it into first but that was it, then it went dead again.

I parked it and first thing I checked was the fluid in the reservoir which looked fine, no change in the level since I checked all the fluids a few days ago, MAYBE like 1/4" lower, not positive tho. I got the car up in the air and looked, it's wet by where the slave bolts up to the trans but I can't tell if it's brake fluid from the master/slave or oil from a leak at the back of the intake mani I haven't totally fixed yet. With the car off I tested the clutch again, pedal is light and goes down to the floor almost where it gets hard. Definitely messed up.

Before I shotgun a new GM master/slave does this sound likely the prob? Any obvious failure signs I can look for besides fluid coming out? (again can't really tell because of a thin sheen of oil on the bellhousing/trans) I'm 99% sure this is the problem because I had sneaking suspicion of its failure for a while due to some other much more minor symptoms but I've gotta scale back on how much money I dump into this thing constantly.

 

Maybe its pushing out fluid and sucking in air - I would check the seal and see if the fluid is contaminated. If you try to bleed it, don't get any in your eye!

The other thing - maybe the master cylinder is shot -
