Vehicle: 1998 E320 with ~80k miles. The oil filler cap appears to accumulate moisture and eventually becomes covered (on the inside) with a 1/4" layer of disgusting creamy oil. It is easy to wipe off, but I'm concerned that the breather system is not working. I have checked the rubber hose leading from the left valve cover across the back of the enginer to the air intlet track just down stream of the mass airflow sensor: it is free of obstructions.
So, has anyone else had this problem? javascript:AddText('[?]');

I'm even considering changing the angle of the port at just downstream of the MAF to create more vacuum. However, this is a unmodified car and all should be well. Very odd.
