So both my wagons leak oil at the oil filter housing to block gasket location. I've pulled the housing off and cleaned both surface areas and think I am ready to re-install with a new gasket. Do I need to put some form a gasket on either side of the gasket? If so this one or this one or this one? If no form a gasket then nothing (or something else?) goes on the gasket- just install clean and tighten the five 6mm allen bolts to around 20fp?
