Hi all,
Just a quick question... How much has to come off the crankshaft in order to replace the seal?
The crankshaft looks so cozy in there.
I REALLY don't want to play with the timing at all.
And, can I loosen just the main caps or do I have to do the rod caps too?

Thanks,
Nathan.

P.S. I have the engine upside down on a stand right now.
