Full pressure lubrication, through a full flow oil filter is furnished by a gear type oil pump. Oil is drawn up through the pickup screen and tube, and passed through the pump to the oil filter. A new priority oil delivery system supplies oil first to the crankshaft journals. Oil from the crankshaft main bearings is supplied to the connecting rod bearings by intersecting passages drilled in the crankshaft. The passages supplying oil to the crankshaft main bearings and the camshaft bearings through intersecting vertical drilled holes. Oil passages from the camshaft journals supply oil to the hydraulic lifters. The hydraulic lifters pump oil up through the pushrods to the rocker arms. Oil draining back from the rocker arms is directed by cast dams in the crankcase casting to supply the camshaft lobes. The camshaft chain drive is lubricated by indirect oil splash.
