    the seal on the rear oil pump could be bad.

    There's around 15 psi in a coolant system. Theres around 40-60psi in the engine crankcase. So oil is going to get forced into the coolant since theres more pressure in there. How many hours are on the ski?

    we rebuilt the engine, new head and pto gasket, new pistons. This engine was one hour only.
