Engine Oiling System

Oil is forced from a gear type oil pump to full-flow oil filter. From the filter, oil is directed to crankshaft main bearings which feeds connecting rod bearings. The oil passage above No. 1 main bearing feeds camshaft and rocker arm shaft through No. 1 rocker support. Oil is then returned to the pan. See Fig 1.
