84 250r crank seal

[bebeav]

i just bought a cheap 84 r and just needed to change piston and rings. now the first time i started it it was smoking a lot of white smoke. after removing the exhaust and checking the plus i found that there was engine oil in my cylinder.

am i right to supose that's the fault of the crank seal??

if i try to break the engine this way will it blow? what bad crank seal could do to my engine???

is there engin oil comein out of your exaust in excess amounts? cuze if so your seals are gone and yes it will blow up trying to run it this way..did you find and rubber chunks caught in the crank when you rebuilt it?

2 stroke oil accumulates in the bottom end. Get it pressure checked at a shop. They'll block of exhuast and intake and pump it up and see if it holds pressure.
