Oil Pump: Description and Operation

An uprated (higher capacity) oil pump is installed to cope with the increased demands of the linear VVT system. The pump is located at the front of the engine and is driven directly by the crankshaft. The intake and outlet ports align with oil passages in the bedplate, with a rubber coated metal gasket to seal the pump to bedplate interface.
An integral pressure relief valve regulates pump outlet pressure at 4.5 bar (65.25 psi).
