CAUTION
The thickness of the original cylinder head gas-
ket is selected according to protrusion amount of
the piston. Therefore, If the cylinder block, pis-
ton, connecting rod or crankshaft is replaced, the
protrusion amount may be changed. Always
select a correct gasket by measuring the protru-
sion amount (Refer to GROUP 11B
− Cylinder
Head and Valves
).

>>B<< CYLINDER HEAD BOLTS INSTALLATION
CAUTION
• Before installing the cylinder head bolt, check
the number of punch marks on its head. (the
bolt is reusable if it is four or less.) The
number of punch marks corresponds to that
to times the bolt has been tightened to the
plastic area. If the bolt has five punch marks,
replace it.
1. Set the cylinder head bolt washer with its shear
droop toward the bolt head.
2. Apply a small amount of engine oil to the thread of
the bolts and to the washers.

mark on the head of the cylinder head bolts
and the paint mark on the cylinder head is on a
linear line.
