Engine Lubrication System: Notes

Lubrication system is a full-flow filtration, pressure-feed type. Oil, stored in oil pan, is taken in and discharged by a rotor type pump directly coupled to crankshaft. Pressure is regulated by a relief valve. Oil is fed through a filter to the crankshaft journals from an oil gallery in the cylinder block. The same gallery feeds oil under pressure to the cylinder heads. Oil flows to each cylinder head, then through passages to camshaft journals, rocker shafts, rocker arms and hydraulic lash adjusters.
