What causes a gasket to displace from the oil filter?
Gasket displacement is the result of insufficient gasket compression during installation, excessive lube system pressure or a combination of the two. Any deformation to the filter, from which the gasket was displaced, is a clear indicator that the filter was exposed to excessive lube system pressure. Excessive lube system pressure is most likely the result of a malfunctioning pressure regulating valve that is failing to open properly.
