Engine Oiling System: Notes

Engine utilizes a force-feed lubricating system. Oil is moved through oil pump to oil filter located on outside of engine block assembly. Lubricant is forced from filter to drilled gallery in center of block where oil moves under pressure to main bearings. Main bearings are drilled to pass lubricant on to rod bearings and to camshaft bearings. Oil from camshaft bearings is pushed up into head assembly where it lubricates rocker arm shaft and rocker arms. Push rods and valve lifters receive oil along with valve assembly. Oil nozzle at front of timing gear recess sprays gears with lubricant directly from main oil gallery. Cylinder walls and rings are lubricated by splash from connecting rods. Excess oil from all areas is returned to sump via drain holes in block assembly.
