4) Make sure that oil jet (venturi plug) (1) is installed and if it is,
that it is not clogged.
When installing it, be sure to tighten to specified torque.
Tightening torque
Venturi plug (a) : 5 N·m (0.5 kg-m, 3.5 lb-ft)
5) Install cylinder head to cylinder block.
Apply engine oil to cylinder head bolts and tighten them
gradually as follows.
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,
14.5 lb-ft) according to numerical order as shown by using
a 12 corner socket wrenches.
b) In the same manner as in Step a), tighten them to 40 N·m
(4.0 kg-m, 29.0 lb-ft).
c) Retighten all bolts 60° according to numerical order in fig-
ure.
d) Repeat Step c).
e) Tighten bolt “A” to specified torque.
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
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.

NOTE:
Be sure to tighten M8 bolt (“A”) after securing the other
bolt.

6) Install ignition coil assemblies referring to “Ignition Coil
Assembly” in this section.
7) Install high-tension cords securely by gripping their caps.
Ignition Coil Assembly (Including Ignitor)
1) Disconnect negative cable at battery.
2) Remove cylinder head upper cover.
3) Disconnect ignition coil connector.
4) Disconnect high-tension cord (3) from ignition coil assembly
(2).
5) Remove ignition coil bolts (1) and then pull out ignition coil
assembly. NOTE:
NGK IFR5E11 or DENSO SK16PR-A11 is highly recom-
mended for better engine starting performance under –
25°C (– 13°F).
CAUTION:
When servicing the iridium/platinum spark plugs (slender
center electrode type plugs), do not touch the center
electrode to avoid damage to it. The electrode is not
strong enough against mechanical force as it is slender
and its material is not mechanically tough.
