A gear-type oil pump is directly driven by the crankshaft and
draws oil from the oil pan, via the suction pipe. If then passes
the pressured oil through a full-flow disposable oil filter, to the
main oil gallery in the cylinder Block. An oil pump pressure
relief valve and oil filter bypass valve are incorporated in the
system.
From the main oil gallery in the cylinder block, the cylinder
head and crankshaft main bearings are supplied with oil.
The camshaft bearings and hydraulic tappets are supplied
through the main feed galleries in the cylinder head. Vent
valves allow air to be expelled from the oil galleries in the
cylinder head. The balance shaft journals are directly fed from
the crankshaft main bearings. The connecting rod bearings are
fed via passages in the crankshaft. The oil returns to the oil
pan via passages in the cylinder block.
