Installing Oil Filter with Lathe Cut Gasket vs. Molded “P Style” Gasket

When installing a spin-on oil filter with lathe cut gasket, the filter should only be hand-tightened ¾-1 turn once the gasket meets the mating surface of the engine. This creates an axial seal as the gasket is compressed between the filter’s baseplate and the engine surface. Installers should NOT take the same approach when installing a filter with a molded gasket. Instead, a molded gasket can be tightened until the baseplate of the filter is touching the surface of the engine. Unlike the case of lathe cut gaskets, there is no danger in doing this with a filter that uses a molded gasket. If installing a filter with a molded gasket and you realize that the filter is touching the surface of the engine, DO NOT back the filter off because this could result in a poor seal and ultimately leak.
