Oil on My Air Filter

Hi Bob,
My air filter element gets oily. How does the oil get on to it?
Alex A.

Alex,
Is it getting oily all around or just in one spot? The reason I ask is because the PCV system returns to the air filter housing. If you have a lot of blowby and are getting excessive amounts of oil in it, then you will see one oily spot on the side of the filter. However, if the filter is oily on the inside, then you are getting oil thrown up through the carb. This indicated a major engine malfunction. Usually bad rings or a blown piston. But, in both cases, it is an indication of a worn engine.
Good Luck!
Drive Safely!
