How does overfilling with oil aerate/foam the oil on a dry sump motor?

Know you know that but just to answer out loud (for the first poster only since that was one of his concerns) since the oil pump return rotor is much larger then the pump pressure side it will not. The crank shaft flywheel rotors never spin in oil..UNLESS the return side of the oil pump has a problem. Then that of course would be another problem.
