Fresh vortech v1 s trim. After driving I get oil on top of my intake, just below where my BOV is located. The BOV has an oily residue on it as well. there is no visible trace of oil in the piping, volute, or around the impeller. Reason tells me it's the impeller shaft seal which is a mechanical ceramic seal, but why oil at the BOV and nowhere else?
