Motorcycle Repair: 2000 RM 80 water in crankcase, crankcase oil, bike bandit

Question
I have replaced head gaskets which reduced the problem, but the water is still finding it's way into the crankcase oil.  I am wondering where to look next.  There are no visible cracks in the head or cylinder.  Any help will be apppreciated.

Answer
Hi Steven,

I suspect the water impeller (pump) seal is defective.

Respectfully,
Mark Shively
