Can you reuse the rear main seal?
 

I know the front always leaks once the balancer has been removed but can you reuse the rear main seal?

Do not do that. Do future YOU a favor and put a new one in

I never reuse any seal once removed.. Save yourself the headache and replace it

^^^ yep

That’s a lot of work to go back and change it if it does leak.

Make sure to read the directions if you haven't installed a new rear seal, as they mostly sale a reverse lip seal now, it goes in reverse compared to the normal.. is important to install correctly as to not leak.. :) peace :)

OP what did you do, change crankshaft, just removed the cover, etc??? I have re-used mine a few times with no leaks.
