Inspection
1. Using a precision straight-edge and
feeler-gauge, measure the surface con-
tacting the cylinder block for warping.
Warpage limit:
0.1 mm (0.004 in)
If the degree of warping exceeds the speci-
fication, re-surface the cylinder head as fol-
lows.
Place 400-600 grit wet-or-dry sandpaper on
the surface-plate, and resurface the cylinder
head by moving in a figure-eight sanding
pattern.
