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. Nonadjustable 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.
NOTE:
Manufacturer recommends changing oil filter at every oil change.
