You should start by completing a compression test. If you have a dead cylinder then the excess fuel can bleed into the oil.

Check your thermostat is not stuck open engine running to cool

Do you do a lot of trolling or low engine revs so engine does not get up to operating temp.

Does the engine reach WOT engine not struggling with to bigger prop

Keakar says that a stuck thermostat can't possibly be the problem.

On the DF140's, the fuel pump is cam driven. When the seals failed on mine, it dumped fuel into the oil. Maybe a similar situation?

regards the other questions prop trolling

it can be if the engine is not reaching op temp as fuel does not boil off is engine reaching op temp ?

I would agree on the fuel pump but it might also be a contaminated injector that is sticking. You would smell fuel in the exhaust and the plugs could be wet fouled with fuel. The excessively rich mixture would blow by the rings and enter the case.
