I don't know that unit but what you are describing is the way an overhead valve engine will act if the oil return from the head is getting pluged. It pumps the oil up into the valve cover untill it cannot hold any more and in doing that emptys the crankcase so rod is not getting oil, setting alows the oil in rocker cover to slowly run back into crancase and that is why it is full again the next morning.
