Disturb crank seal?

[Struggler]

I'm really on the fence about resealing the rear (flywheel) crank seal.

I know it's a common leak point and people recommend doing it, but on the other hand this is all the leaking it's done since new (1999) so I'm not sure if it's better to just leave it than disturb it.

Having been in your predicament, deciding to replace it putting it back together and it leaking again after a dyno session, I’m definitely on the side of leave it alone unless it’s pissing out. I was not happy pulling it apart again.

I would change it, pull the cap, re seal it and a fresh seal, just make sure the crank is clean where the seal sits and use a proper seal driver to make sure it goes in square.

I’m team leave it. I’m mid rebuild and not changing mine.

Although I know that freaks many people out.

I'd do it, in general very few new seals leak
