• CYLINDER HEAD WARPAGE
1) Remove the carbon deposits from the combustion
chamber. Clean off any gasket material from the cylinder
head surface.
2) Check the spark plug holes and valve seats for cracks.
3) Check the cylinder head for warpage using a straight edge
and a feeler gauge.
Standard Service limit
Less than 0.05 mm 0.10 mm
(0.002 in) (0.004 in)
4) If the measurement exceeds the service limit, recondition
the cylinder head.
Cylinder head reconditioning procedure:
Apply Prussian Blue compound to the level block to identify
the warpage, and using a fine oil stone, grind the cylinder
head in a "figure 8", with the warped part being the center
of the ground part. Or use the lapping machine to
recondition the cylinder head.
