I saw your Aug post on inverted engines. Question: if one were to invert an inline 4 cyl, do you preceive a problem with oil accumulating in the underside cavity of the pisons (the rod side) and sapping power due to the sloshing of the oil up and down? Potentially this problem could also affect a V-8 where the oil would get sloshed back and forth to the alternate side of the V. Must not be a problem but I'm trying to anticipate everything.
