Engine Lubrication System

The camshaft-driven gear-type oil pump provides pressurized lubrication through the oil filter, to main gallery above left side of camshaft center line. The main gallery provides lubrication to valve lifters on left bank, camshaft bearings, crankshaft bearings and right gallery.

The right gallery supplies oil to valve lifters on right bank. Rocker arms are lubricated by passages in the push rods. Slot in front camshaft bearing provides lubrication to timing chain. Pistons and piston pins are lubricated by oil splash. Pressure regulator valve is mounted in oil pump body.
