Hey, if you use one of those dual filter kits, think about getting it powder coated. We used to use them a lot on VW dune buggies (they only hold 2 1/2 quarts stock) and there was always oil everywhere, but we could never figure out where it was from. One of the guys had his powder-coated and that solved it. The way it was explained to me is the aluminum was porous enough to allow oil to seep thru it. I didn't believe it, but Al's car didn't have the film of oil all over it like the rest of us. FWIW. Also, always believe more oil is better.
