I'm in the middle of replacing my clutch, and there's no signs of an oil leak around the flywheel. It's dry as a bone in there. I'm aware of the "while I'm in there" belief, but I'm a member of the "if it ain't broke don't fix it" camp, so I'm stuck whether or not to replace the main and oil pump seals. I'm looking for some convincing either way. What do you guys think?
