Cylinder Head Assembly: Description and Operation
CYLINDER HEADDESCRIPTION
The cross flow designed, aluminum cylinder head contains a single over head camshaft with four valves per cylinder (Fig. 14). The valves are arranged in two in-line banks. The intake valves face toward the front of the vehicle. The exhaust valves face the dash panel. The cylinder head incorporates powdered metal valve guides and seats. The cylinder head is sealed to the block using a head gasket and retaining bolts.
The rocker arm shafts mount directly to the cylinder head. The rocker arms shafts are hollow, providing lubrication passages to the hydraulic lash adjusters, camshaft, and valve mechanisms.
