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 Oiling System
A camshaft-driven, gear-type oil pump provides pressurized lubrication through oil filter, to main gallery above left side of camshaft center line. This gallery provides lubrication to valve lifters on left bank, camshaft bearings, crankshaft and right gallery. See Fig 1.
The right gallery supplies oil to valve lifters on right bank. Rocker arms are lubricated by passages in push rods. Slot in front camshaft bearing provides lubrication to camshaft thrust face. Pressure regulator valve is mounted in oil pump body.
