LUBRICATION
DESCRIPTION
The lubrication system is a full flow filtration pressure feed type.
OPERATION
Oil from the oil pan is pumped by a gerotor type oil pump directly mounted to the crankshaft nose. Oil pressure is
controlled by a relief valve mounted inside the oil pump housing.
The camshaft exhaust valve lobes and rocker arms are lubricated through a small hole in the rocker arm; oil flows
through the lash adjuster then through the rocker arm and onto the camshaftlobe. Due to the orentation of the
rocker arm, the camshaft intake lobes are not lubed in the same manner as theexhaust lobes. The intake lobes are
lubed through internal passages in the camshaft. Oil flows through a bore in the number 3 camshaft bearing bore,
and as the camshaft turns, a hole in the camshaft aligns with the hole in the camshaft bore allowing engine oil to
enter the camshaft tube. The oil then exits through 1.6mm (0.063 in.) holesdrilled into the intake lobes, lubricating
the lobes and the rocker arms.
