Abstract
A reusable oil filter assembly adapted for use in filtering the lubricating oil of an engine configured to receive an oil filter, including a filter housing having an open end and a closed end, a filter mount disposed between the filter housing and the engine for receiving the unfiltered oil from the engine and returning filtered oil to the engine. The filter mount includes a first plate, a second plate, and an anti-drain back seal disposed between the first plate and the second plate. The anti-drain back seal prevents both the oil disposed in the engine from flowing out into the filter assembly and the oil disposed in the filter assembly from flowing into the engine when the engine is turned off. The first plate, the second plate and the anti-drain back seal are fittingly, rather than integrally, mated together, thus facilitating service, repair and replacement of the assembly. A reusable filter cartridge registers with the filter mount inside the chamber to receive from the engine unfiltered oil from regions exterior of the cartridge and to return to the engine filtered oil from regions interior of the cartridge.
