Answer 1

if you have a 2 cycle engine,oil is add to the gas,and you might not have the correct ratio ( gas and oil mix) to much oil would cause this. if it a 4 cycle engine you might have to much oil in crank case,or you might have turn the engine over on it side and oil ran in your carb.good luck.

Answer 2

An old worn engine with poor rings will do this. It may still run for awhile that way though. Some engines have a crankcase vent tube into the intake. you can reroute this tube to blow out the side.

Answer 3

Worn out piston, rings and cylinder wall,usually caused by dirt ingestion.Or if it is a overhead valved engine, it could be a blown head gasket.

Answer 4

The oil level is the crankcase is too high.  The oil will go through the crankcase vent line into the air filter box and into the carb from there.
