Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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 cylinder heads. Oil flows to each cylinder head, then through passages to camshaft journals, rocker shafts, rocker arms and hydraulic lash adjusters. See Figure.
