You will have to split the cases to change the outer seals anyway so I would just fill the outer seals with silicon and run a few more tests to see if the centre seal is leaking. Chances are it is leaking and even if it's not, how much longer will it last if reused?

I personally would have the crank rebuilt if you plan on keeping the bike.

Must say that I did notice you were not posting but still checking the forum for the last 6 months. Hope your all healed up now.
