4) Make sure that oil jet (venturi plug) (1) is installed and if it is,
Tightening torque
Venturi plug (a) : 5 N·m (0.5 kg-m, 3.5 lb-ft)
5) Install cylinder head to cylinder block.
NOTE:

If cylinder head bolts are reused, check thread diameters
of them for deformation according to the following and
replace them with new ones if thread diameter difference
exceeds limit.
Measure each thread diameter of cylinder head bolt (1) at
"A" on 83.5 mm (2.81 in.) from seat side of flange bolt
and "B" on 115 mm (4.53 in.) from seat side of flange bolt
by using a micrometer (2).
Then calculate difference in diameters ("A" – "B").
If it exceeds limit, replace with new one.
Cylinder head bolt diameter measurement points
"a" : 83.5 mm (2.81 in.)
"b" : 115 mm (4.53 in.)
Cylinder head bolt diameter difference (deformation)
Limit ("A" – "B") : 0.1 mm (0.004 in.)
a) Tighten cylinder head bolts ("1" – "10") to 20 N·m (2.0 kg-m,
b) In the same manner as in Step a), tighten them to 40 N·m
c) Retighten all bolts 60° according to numerical order in fig-
d) Repeat Step c).
e) Tighten bolt "A" to specified torque.
NOTE:
Be sure to tighten M8 bolt ("A") after securing the other
bolt.
Tightening torque
Cylinder head bolt for M8 (a) : 22 N·m (2.2 kg-m, 16.0 lb-ft)
Cylinder head bolts for M10
(b) : 40 N·m (4.0 kg-m, 29.0 lb-ft) and extra tightening 60°
twice
that it is not clogged.
When installing it, be sure to tighten to specified torque.
Apply engine oil to cylinder head bolts and tighten them
gradually as follows.
14.5 lb-ft) according to numerical order as shown by using
a 12 corner socket wrenches.
(4.0 kg-m, 29.0 lb-ft).
