ABSTRACT:
An oil pump cover is provided which converts a standard Volkswagen type air-cooled engine into a full flow oil system for the installation of auxiliary oil filters and coolers by merely replacing the standard oil pump cover with the cover of the present invention. The cover includes a baffle for segregating a discharge chamber of the oil pump into a first (outlet) compartment and a second (return inlet) compartment. The cover includes an outlet recess for communicating with the first compartment and has an outlet passage extending from the outlet recess to the exterior of the cover, forming an outlet. The cover further includes an oil return inlet recess for communicating with the second compartment and has a passage extending from the inlet recess to the exterior of the cover forming a return inlet. The auxiliary oil filter or cooler is installed at a remote location on a vehicle and is connected by suitable hoses to the inlet and outlet of the oil pump cover.
