Rear main seal leak? *DUW*

ok, i don't think the seals are bad ... i 'll pull the springs off that cylinder and take pics of the seals

my hypothesis is that it blew one or more of the oil rings only, but the compression rings are ok :shrug:

could increased crankcase pressure from the kb have caused the main seal to go?

hehe that is also my "excuse" for building a new motor!
