Abstract:
A camshaft cover mounts to a cylinder head and defines cavities for oil control valves that adjust the position of camshafts via camshaft phaser assemblies. The cavities are positioned above the camshafts when the camshaft cover is mounted to the cylinder head. A feed passage communicates pressurized fluid from the cylinder head to the cavities when the camshaft cover is mounted to the cylinder head. Control passages communicate fluid from the cavities to the camshaft phaser assemblies when the camshaft cover is mounted to the cylinder head.
