Mine was a TINY pin hole in the non hard line from the firewall to the Slave cylinder. Replaced it with a new line and all was well.1) Clutch: Going to try and get it vacuum bled like GF8er suggested in one of my other posts. If not, guess ill try replacing the slave then the master.
2) Headgasket: Ordered my new cometic HG last friday. Should have it tomorrow. Then should have it all fixed and ready to go for friday. Have 160 miles on the motor so far. Want to be able to at least be able to break in the clutch.
I tried a SS line and vacuum bleeding/manual bleeding. Then the rubber went on, and it was magic.
