Cylinder head for Nissan ZD30

The cylinder head, part number 908509, mounts to the top of the engine block to seal the cylinders and create the combustion chambers where the air and fuel mixture ignites. This component houses the intake and exhaust valves, valve seats, valve guides, and provides mounting points for injectors. It also features internal passages for coolant circulation and oil flow to assist with thermal management and lubrication within the engine assembly.

This component is compatible with the Nissan ZD30 and Nissan ZD30 LEVAS/WITH engine configurations. It is designed to maintain the required compression levels and ensure the proper sealing of the combustion process. By providing a secure interface between the engine block and the valve train, it supports the operational requirements of the engine.

A cylinder head functions as the primary cover for the engine cylinders, housing the valve train and managing the flow of gases and fluids. It allows for the intake of air and fuel and the exhaust of combustion gases while maintaining a pressure-tight seal against the engine block under varying operating temperatures.
