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 through oil filter to main oil gallery. To journals of camshaft and crankshaft. From there, oil goes to main bearings, piston pin bushings and cylinder walls. Oil then passes through valve lifters and push rods to oil rocker arms.
