May has been an unlucky Month for me. Especially this May. One of the things that happened is I did an Oil Change and when I put 5 quarts of new Oil it did not go into the Engine but down on my Driveway.

Unseen was the fact that the Oil Fill Pipe had pulled out entirely from the Valve Cover Grommet leaving a open hole and no way for the new oil to get into the Engine.

Since for over 6 Months I had occasionally been smelling Oil Vapor I had been driving with that Oil Fill Pipe disconnected.

Next is I had to have a smog/emission tests and despite the fact that I passed last year after installing a new Catalytic Converter. I failed with high HC and CO emissions.

Now I am wondering what 6+ Months of driving with the Oil Fill Pipe disconnected messed with concerning the positive crankcase pressure and what effect that would have? Which is my question to you all.
