Cylinder Head and Valve Train
The cylinder head is a one piece, crossflow design with
two valves per cylinder. The head has integrally cast
valve guides and hardened valve seat surfaces which
can be repaired in a machine shop using the appropriate
service parts.
The cylinder head has a cast intake manifold, fuel filter
head, thermostat housing and an internal water bypass.
The injectors are mounted in the head for direct injection
into the cylinders.
Separate pedestals for each cylinder are used to support
and route oil to the rocker levers.
The cylinder head gasket is a laminated design with
print-o-seal on both sides around the water holes. A fire
ring in the gasket seals the cylinder bores. As discussed
in the Cooling System, the gasket also provides orifices
to control coolant flow.
