Engine Oiling System: Notes

Lubrication system is a force feed type with a full flow oil filter. A rotor type oil pump located in the crankcase and driven by a shaft connected to distributor drive gear provides oil to all parts of the engine. Oil pump forces oil through the oil filter. After leaving oil filter, oil travels through a drilled passage in engine block to an oil gallery. One secondary passage from this main passage goes to the rear balance shaft bearing. From oil gallery passages go to crankshaft main bearings, camshaft bearings, rocker arm assemblies and front balance shaft bearing. Connecting rods receive oil from passages in crankshaft which are connected to main bearing journals. A spray hole in connecting rods lubricates pistons and cylinder walls.
