[Mgs] Clutch Master Cylinder Barfing

[Max Heim]

Folowing up on the other clutch cylinder thread...

Maybe somebody rebuilt the clutch MC, and "overhoned" it. In extremely cold
weather the metal shrinks and it loses the seal. Just a theory. Or the seals
could just be old and hard -- same effect.

I would agree about the TO bearing.
