One thing that has bothered me since I had my oil tank welded up is not providing for a way to decrease the chance of oil foaming. It's a problem that is emphasized to prevent when running a radial engine with a remote oil tank. As I had it, oil would return to the tank at the top of the tank, pouring straight down unimpeded. Like pouring a beer straight into a mug, and getting a whopper of a head. Add to that, the level of the oil would be reduced while the engine is running, making the length of drop even higher, causing even more foaming. So a simple solution was searched for before a wholesale revamp of the tank was done. I came up with inserting an angled baffle across the back of the tank positioned under the return fittings that directs the oil toward the back wall of the tank. Again using the pouring a beer along the side of a mug to prevent creating a big head analogy. So I made two slits in the tank and inserted a piece of .050 aluminum. Again, master welder Craig welded it up for me. I'm a bit more comfortable with the result, warranted or not.
