The front and rear camshaft bushings receive oil from
a hole in the respective rocker arm shaft. A drilled
passage lines up with a drilled passage in the head to
route oil to the bushings.
The rocker arm shaft is cross-drilled to provide
lubrication to each rocker arm bushing.
The unit injector rocker arms (Q) are cross-drilled to
route oil from the bushing to each end of the rocker
arm. At the roller end, oil flows through the roller
bushing (R) and out to spray and lubricate the
adjacent valve rocker arm rollers (S). Oil then sprays
on to the camshaft lobes.
At the front of the unit injector rocker arms, oil sprays
out the adjusting screw to lubricate the unit injector (T)
and the adjacent valves and adjusting screws.
Some oil is routed from the top of the oil filter base
through an external line to the turbocharger and is
returned to the cylinder block crankcase through
another external line.
