Bush Carrier

This contains the oil passages that link the engine oil supply to the Valve Timing (VVT) unit. A lug on the bush carrier locates in the central bore of the VVT unit.
Two hollow dowels at the bush carrier and cylinder block ensure that the lug is accurately located. A scarf jointed fiber ring seals the joint between the lug and the valve timing unit. An integral shuttle valve, biased by a coil spring, controls the oil flow to the VVT unit.
