Engine Oiling System: Notes

Oil is pressure fed by a camshaft driven trochoid type oil pump. Pump incorporates an oil relief and by-pass valve in its body. Oil pump is located externally on engine. Oil from pump passes from main oil gallery to journals of camshaft and crankshaft. From there, oil goes to main bearings, piston pin bearings and cylinder walls. Oil passes through valve lifters and push rods to oil rocker arms.
