Engine Lubrication: Notes

A full-flow oil filter and trochoid-type oil pump are used. The oil pump delivers filtered oil to main oil gallery and crankshaft journals. Oil passages in crankshaft feed oil to connecting rod journals. Engine cylinder bore and piston pins are lubricated by oil spray from oil jet located on connecting rods.

An oil passage from No. 3 crankshaft journal delivers oil to cylinder head. Oil is fed to rocker arms by oil ports in rocker arm shaft assemblies. An oil well on top of cylinder head provides lubrication for camshaft.
