Engine Lubrication: Notes

Oil is circulated through the engine by pressure provided by a rotor-type oil pump. Pump is mounted on bottom of crankcase and is driven by camshaft through distributor drive. Oil is drawn from oil pan and is circulated through a full-flow oil filter into main oil galley. Oil is then distributed to main and connecting rod bearing journals and camshaft bearing journals.

Cylinders and piston pins are lubricated by oil spraying from a hole in connecting rod. Oil is supplied to timing chain by oil from timing chain tensioner. Oil flows from No. 2 cam bearing journal to rocker arm shaft to lubricate rocker arms. Excess oil from rocker arm shaft lubricates valves and valve stems.
