sure the warpage on the surfaces which contacts the cyl-
inder block and manifolds.
Maximum warpage:
0.05 mm (0.0020 in.) for cylinder block surface

Do not rotate the valve.
(c) Check the valve face and seat according to the following
procedure.
(1) If blue appears 360 around the face, the valve is
concentric. If not, replace the valve.
(2) If blue appears 360 around the valve seat, the
guide and face are concentric. If not, resurface the
seat.
(3) Check that the seat contact is in the middle of the
valve face with the width between 1.0 and 1.4 mm
(0.039 to 0.055 in.).
18. REPAIR VALVE SEATS

bottom of the piston and at a right angle (90) to the piston
pin holes as illustrated.
Piston diameter:
91.953 to 91.967 mm (3.6202 to 3.6207 in.)
20. INSPECT PISTON OIL CLEARANCE
(a) Subtract the piston diameter measurement from the cylinder bore diameter measurement.
