Abstract: A combination of electrical, mechanical and hydraulic components specifically arranged in communication with the existing lubrication system of high performance internal combustion engines, such as are utilized in the motor home industry, so as to enable the pre-lubing of the moving parts of the engine before it is started or turned over, the components of which are existing items of manufacture and the combination can be readily installed by owners without expensive modifications to the engine, said prelube system being primarily comprised of the removal of engine oil from the oil pan sump, pressurization of the oil by an electrically-driven pump and reinsertion of the oil into the engine through a one-quarter inch pipe Tee adapter, placed between the oil-sender and the engine block at the end of the engine farthest away from the engine-driven oil pump, said prelube system being controlled by a manually-activated electrical switch on the dashboard of the vehicle.
