or put a cover on where it was designed to go but the chinaman decided it wasnt needed. maybe chinaman thinks air filter should be oiled. the cover makes the vapor turn a couple times and the oil ends up on the wall of the air box and drains back down into engine or into the intake. shouldnt be a lot of oil though. if there is a lot then you over filled probably cause the manual calls for 1.6 quarts and chinaman is wrong again its just barley over a quart to fill it to correct level. like everyone else said check sight glass when level.
