CYLINDER HEAD
DESCRIPTION
The aluminum alloy cylinder heads feature cross-
flow type intake and exhaust ports. Valve guides and
seat inserts are powdered metal. Valves are arranged
in a “V”, with each camshaft on center. To improve
combustion speed the chambers are a compact spher-
ical design with a squish area of approximately 30
percent of the piston top area. The cylinder heads are
common to either cylinder bank by reversing the
direction of installation.
DIAGNOSIS AND TESTING—CYLINDER HEAD

A cylinder head gasket leak can be located between
adjacent cylinders or between a cylinder and the
adjacent water jacket.
Possible indications of the cylinder head gasket
leaking between adjacent cylinders are:
• Loss of engine power
• Engine misfiring
• Poor fuel economy
Possible indications of the cylinder head gasket
leaking between a cylinder and an adjacent water
jacket are:
• Engine overheating
• Loss of coolant
