Hi,
Who is the manufacturer of the vehicle? I was thinking it was a Chevrolet Lumina. As far as the pics, I copied one and circled a hose running to the intake. It isn't connected. Do you know where that is going to?
As far as oil in the air filter, it could be a few different things. Is the mileage you indicated above (300,000) miles, correct? It simply could be the result of excessive crankcase pressure due to worn piston rings.
How much oil is getting into the air filter box? Also, let me know about the hose in the pic I attached below.
Take care,
Joe
