These are the minor improvements I did in winter - spring 2017. - Repainted canister oil filter. I removed my spin-on oil filter conversion because it was leaking. I installed the old canister with a new filter, new gasket, and that leaks too. Bah!! Maybe new copper washers will help? - Borrowed a UV light and did a dye test to try to account for all my oil leaks. For some reason, my drain plug leaks only when the engine is running. First I will try a new washer on the plug ... after that I may consider installing a drain cock that I don't need to unthread every time. - Tracked down and installed a stock fan shroud from a 6-cylinder car. The shroud is long enough that the fan reaches it with a medium sized spacer. I pulled the electric fan out and it cools better than ever. - Repainted and reinstalled the oil bath air filter. Really helped the appearance under the hood -- and it's amazing how well the oil bath quiets intake noise.
