Oil Filter
This engine uses a combination pressure/splash lubrication system, delivering oil under pressure to crankshaft,
connecting rod and main bearing surfaces. Other component areas are splash lubricated.
A high-efficiency gerotor oil pump maintains high oil flow and oil pressure, even at low speeds and high operating
temperatures. A pressure relief valve limits maximum pressure of system. Oil pan must be removed to service oil
pickup and oil pump.
