Your symptoms describe an engine that is sludged up on the top end and the oil is not draining back quickly enough. Pull a valve cover to confirm this. If the engine is sludged, the top of the head will be covered in sludge and the drain holes will be partially blocked.
NightWing,

This is exactly what I think is happening. All the oil is stuck up top and cannot get back to the sump pump.
