"DA CYLINDER HEAD GASKET INSTALLATION
(1) Select a cylinder head gasket of the correct thickness
according to the projecting height of the pistons. The
available cylinder head gaskets are shown in the table
below. The thickness of the gasket is indicated by the
number of holes near the end of the gasket (see the
illustration). Measure the projecting height of the pistons.
Based on the highest projection, select a cylinder head
gasket of the correct thickness from the table shown below.
Highest piston
height above
cylinder block mm
Number of holes Gasket thickness
mm
< 0.653 2 1.35
0.653 – 0.786 1 1.45
0.786 > 3 1.55
When only the gasket is to be replaced, check the hole
pattern on the old gasket and select a gasket with the
same number of holes.
Caution
D If a piston or connecting rod, etc. has been
replaced, always measure the projecting height
of the pistons because this may have changed
after replacing these parts.
"EA CYLINDER HEAD BOLT INSTALLATION
Caution
D Do not reuse the cylinder head bolts once removed.
(1) Fit the washers.
(2) Tighten all the bolts to 30 Nm, then angle-tighten by 50_
± 4_ in the order shown in the illustration at left.
(3) Wait three minutes for gasket to settle.
(4) Slacken bolts 1 – 2 until they are completely free.
(5) Tighten bolts 1 – 2 to 25 Nm, then angle-tighten by 213_
± 7_.
(6) Carry out the same slackening and torque/angle tightening
operations on the remaining bolts 3 – 4, 5 – 6, 7 – 8,
9 – 10.
