Recently I bought a set of SBC Mickey Thompson valve covers to put on my 350 crate motor. They are probably 70's era and in great shape. I had them powder coated in satin black and then sanded down the high spots to give me the look I wanted in my engine compartment (see photo). As I started to install them today I realized they have no baffles. A motorhead friend said I must have at least one baffle beneath the PCV Valve or oil will make a mess. He said I have to add a baffle or get a special rubber grommet that is longer with a slit at its bottom. I found some of the longer grommets on EBAY but they are 1.22" and I need 1". Should I enlarge the hole and get a bigger PCV valve or try to add a baffle to that cover? I'd hate to drill holes in the cover to add a baffle. Has anyone had a similar problem?
