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 Trocoid type pump directly coupled to crankshaft. Pressure is regulated by a relief valve. Oil is fed through a filter to crankshaft journals from an oil gallery in cylinder block. Same gallery feeds oil under pressure to cylinder heads and camshaft journals. Oil then flows from cylinder head passages to rocker shafts, rocker arm pivots and auto lash adjusters. See Fig 1.
