I just reinstalled the engine in my 1995 chevy k1500 work truck. On the
bottom of the slave cylinder was a hex head screw. I took it out and pushed
the rod back far enough that I could now get the cylinder bolted in place on
the bell housing. When I put the screw back in it does not tighten. Goes
flush with cylinder case then keeps on turning in place. Is this normal? I
would think it would leak.
