NO! Do not replace the head gasket. There is nothing related to the head gasket. The oil splashes around in the valves and seems to find any opening it can to get out. Replacing the valve cover gasket was ok but the grommets on the top of the plug wells need to be replaced as well. Do this soon, any problems with performance of the engine in the near term are possibly related to a cracked plug or bad wire do to the oil leak.
