Disassembly

NOTE:

f

During disassembly, be sure that the valve train
components are kept together and identified so that
they can be reinstalled in their original locations.

f

Before removing the cylinder head from the engine
and before disassembling the valve mechanism,
perform a compression test and note the results.

1. Remove camshaft drive gear pulley fixing bolt (3),

then pulley (4).

Clean

Cylinder head

Carefully remove all varnish, soot and carbon from the
bare metal. Do not use a motorized wire brush on any
gasket sealing surface.

Inspection and Repair

1. Cylinder head gasket and mating surfaces for leaks,

corrosion and blow–by. If the gasket has failed,
determine the cause.
– Insufficient torque on head bolts
– Improper installation
– Loose or warped cylinder head
– Missing dowel pins
– Warped case surface

2. Cylinder head for cracks, especially between valve

seats and in the exhaust ports.

3. Cylinder head deck for corrosion, sand particles in

head and porosity.

CAUTION:

f

Do not attempt to weld the cylinder head. Replace
it.

f

Do not reuse cylinder head bolts.

4. Cylinder head deck, common chamber and exhaust

manifold mating surfaces for flatness. These
surfaces may be reconditioned by milling. If the
surfaces are “out of flat” by more than specification,
the surface should be ground to within specifications.
Replace the head if it requires machining beyound the
repairable limit.

Head surface and manifold surface
Standard: 0.05 mm (0.002 in) or less
Warpage limit: 0.2 mm (0.0079 in)
Maximum Repairable limit: 0.2 mm (0.0079 in)

Head height
Standard height : 133.2 mm (5.2441 in)
Warpage limit : 0.2 mm (0.0079 in)
Maximum Repairable limit : 133.0 mm (5.2362 in)
