Engine Oiling System

A gear-type oil pump provides full pressure lubrication through full flow oil filter. Oil is drawn up through screen and tube, and passed through pump to oil filter. From the filter, oil is routed to main oil gallery and through drilled holes above camshaft (to left of camshaft centerline) and on to lifters.

Lifter pumps oil through push rods to rocker arms. Oil draining back from rocker arms is directed by cast dams (part of crankcase casting) to supply camshaft lobes with oil. Passages supplying oil to camshaft bearings also supply crankshaft bearings through passages drilled in crankshaft.
