Pressure System - Cylinder Head
Filtered oil is fed to the rear of the cylinder head from the crankshaft number four main
bearing to supply oil to the low oil pressure warning switch and the camshafts. After the
oil pressure switch, the oil is divided into two drillings in the cylinder head to supply oil
to both camshafts at the number four camshaft cap. Through drillings within the
camshafts oil is fed to numbers three and two camshaft caps. Oil lubricates the camshaft
bearings and spills out onto the valve buckets and valve springs.
Filtered oil is fed to the front of the cylinder head from the crankshaft number one main
bearing to supply oil to the camshaft drive chain tensioner and the number one
camshaft cap. Oil lubricates the camshaft bearings and spills out onto the camshaft
sprockets.
Oil returns to the sump through the camshaft drive chain area, lubricating the camshaft
drive chain. Oil also returns through a drilling in the rear of the cylinder head.
