How common is it to have cylinder leakage coming from the crankcase in an OM603? If the bottom end is leaking then things can get expensive and i'll be better off hunting for a used short block.

I'm hoping the leakage is from the air intake and exhaust valves from the head, then I can get the head rebuilt and be fine.

Don't forget to grease the screw and threads on the spring compressor.
