Clean
Cylinder head
Carefully remove all varnish, soot and carbon from the
bare metal. Do not use surface conditioning disc on any
gasket sealing surface.
Inspection and Repair
1. Inspect 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. Inspect cylinder head for cracks, especially between
valve seats and in the exhaust ports.
3. Inspect cylinder head deck for corrosion, sand
particles in head and porosity.
CAUTION:
Do not attempt to weld the cylinder head. Replace
it.
Do not reuse cylinder head bolts.
4. Inspect cylinder head deck, common chamber and
exhaust manifold mating surfaces for flatness. These
surfaces may be reconditioned by milling. If the
surfaces are ªout of flatº with ªroundº by more than
specification, the surface should be ground to within
specifications. Replace the head if it requires
machining beyond 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)
