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
Pressurized lubrication is provided by gear-type oil pump. See Fig 1. Camshaft drives oil pump through shaft of a gear-driven engine speed sensor. Lubrication flows through external oil cooler then into full-flow oil filter. Non-adjustable oil pressure regulator valve is located in oil pump body. Main oil gallery supplies oil through drilled passages to camshaft and crankshaft bearings. Oil flows through galleries to valve lifters, then through hollow push rods to rocker arms.
