Help!! -- Clutch Issue
I have a 85 with the 4+3
Last night to it out drove around everything was fine..
parked it in the garage when I got home..
Today I get in it.. I push the clutch in to start it..
and the clutch goes to the firewall with no resistance except for like the last inch..
I noticed that if I pump the clutch resistance builds..
So.. I
Check the fluid level of the clutch... Fine.
next..
I start it up drive around the block.. shifts fine through the gears
come to a stop.. No resistance again.. cant even take it out of gear..
"runaway corvette" shut it off... start pumping the clutch again.. resistance comes back.. start it up and get it back home..
check the fluid level again... Low now..
My thought clutch master cyclinder went bad.. seals..
feels like the same when brake cyclinder goes out..
Any thoughts on this guys I need to get it running ASAP..
Thanks for the help.

You have a leak, 99% it's a bad cylinder.
Don't drive it like this. I nursed mine like this before buying the new master cylinder, and killed my synchros (because of the clutch not disengaging all the way when shifting)
Even after a few gear oil flushes to get all the metal shavings out of the 4 speed, it still shifts hard, and pops out of 3rd gear at high rpms.
If you remove the clutch hose from the slave cylinder, you need to buy new bronze crush washers from GM to put in there, or it'll never seal.
