Oil supply from pan is forced through lubrication system by rotor oil pump. Oil flows through full-flow oil filter, which routes oil into main oil gallery. See Figure.
Oil gallery supplies oil to all internal engine bearings and lifters. Oil from lifters is forced through push rods to lubricate valve train. Timing gears are lubricated by splash method. Spring-loaded oil pressure relief valve is located in pump body and is nonadjustable.
