This unit has about 2800 hrs. on it and the engine pumps oil up into the air cleaner and chokes it out when it gets warm. What needs to be done to correct this problem?

That is caused by too much oil in the crankcase or too much pressure in the crankcase.
Usual suspect is a blown head gasket.
Not very accurate test is to run the engine for 10 minutes or more stop the engine then remove the dip stick.
If you get smoke coming out the head gasket is gone.
