With your compression numbers, I would say one of your piston rings is shot. When you did the compression test, it pressurized the crank case (thru the bad piston ring) and forced oil thru your head gasket. While the head gasket may not be completely blown, having oil seep from it indicates the head bolts are not torqued correctly and/or the gasket is on it's way to being blown out.
