One other thought..In the VW Bug, isn't the finned oil pan subject to cooling air (separate from the Cooling for the jugs) from under the vehicle as it drives? If thats so , then it stands to reason that mayby they should have it in the planes also. i know that lots or perhaps NONE of the planes do it that way..but the question still begs answering.
