An oil filter assembly includes a filter housing and a release valve for regulating oil drainage from a filter chamber in the filter housing. A filter module is arranged in the filter chamber to engage the release valve. A first biasing element normally moves the release valve to an opened position allowing drainage of oil from the filter chamber to urge the filter module to cause the release valve to move against and overcome a biasing force generated by the first biasing element to the closed position when the filter module is installed in a oil-filtering position in the filter housing.
