Good afternoon,

The most common cause is the PCV system. If the system is not working correctly, oil will be forced into the air filter from crankcase pressure.

Beyond that, the piston rings in the engine are bad causing too much pressure.

It will be most likely pistons rings in the motor. That is a major repair.
