REASSEMBLY
HINT:

Thoroughly clean all parts to be assembled.

Before installing the parts, apply fresh engine oil to all slid-
ing and rotating surfaces.

Replace all gaskets and oil seals with new ones.
1. INSTALL SPARK PLUG TUBES
HINT:
When using a new cylinder head, spark plug tubes must be
installed.
(a) Apply adhesive to the end of the spark plug tube.
Adhesive:
Part No. 08833±00070, THREE BOND 1324
or equivalent
(b) Using a wooden block and hammer, tap in a new spark
tube until there is 40.9 ± 42.1 mm (1.610 ± 1.658 in.) pro-
truding from the camshaft bearing cap installation surface
of the cylinder head.
NOTICE:
Avoid tapping a new spark plug tube too far for measuring
the amount of the protrusion while tapping.
2. INSTALL VALVES
(a) Using SST, push in a new oil seal.
SST 09201±41020
(b) Install the valve (1), spring seat (2), valve spring (3) and
spring retainer (4).

(c) Install the heat insulator with the 4 bolts.
Torque: 7.5 N´m (76 kgf´cm, 66 in.´lbf)
3. PLACE CYLINDER HEADS ON CYLINDER BLOCK
(a) Place 2 new cylinder head gaskets in the positions on the
cylinder block.
HINT:
On the rear side of the cylinder head gasket are marked to dis-
tinguish the LH and RH banks, a º2URº mark for the RH bank
and a º2ULº mark for the LH bank.
NOTICE:
Be careful of the installation direction.
(b) Place the 2 cylinder heads in the positions on the cylinder
head gaskets.
4. INSTALL CYLINDER HEAD BOLTS
HINT:

The cylinder head bolts are tightened in 2 progressive
steps (steps (c) and (e)).

If any cylinder head bolt is broken or deformed, replace
it.
(a) Apply a light coat of engine oil to the threads and under
the heads of the cylinder head bolts.
(b) Install the plate washer to the cylinder head bolt.
(c) Install and uniformly tighten the 10 cylinder head bolts on
one side of the cylinder head in several steps in the se-
quence shown, then perform the same procedure to the
other side as shown.
Torque: 40 N´m (408 kgf´cm, 30 ft´lbf)
If any of the cylinder head bolts does not meet the torque speci-
fication, replace the cylinder head bolt.

(4) Install the camshaft housing plug to the cylinder
head as shown in the illustration.
(5) Install the strainer to the cylinder head.
NOTICE:
Be careful of the installation direction.
(6) Apply seal packing to the front bearing cap.

Remove any old packing material (FIPG) and
be careful not to drop any oil on the contact
surfaces of the bearing cap and cylinder
head.
Using a razor blade and gasket scraper, re-
move all the old packing material (FIPG) from
the gasket surfaces and groove.
Thoroughly clean all components to remove
all the loose material.
Using a non±residue solvent, clean both
sealing surfaces.

Apply seal packing to the bearing cap as
shown in the illustration.
Install a nozzle that has been cut to a 1.5 mm
(0.059 in.) opening.
Parts must be assembled within 5 minutes of
application. Otherwise the material must be
removed and reapplied.
Immediately remove the nozzle from the tube
and reinstall cap.
Seal packing: Part No. 08826±00080 or equivalent
NOTICE:
Do not apply seal packing to the front bearing cap grooves.
(7) Install the front bearing cap.
HINT:
Installing the front bearing cap will determine the thrust portion
of the camshaft.
(8) Install the other bearing caps in the sequence
shown with the arrow mark facing forward.

3. CLEAN PISTON
(a) Using a gasket scraper, remove the carbon from the pis-
ton top.
(b) Using a groove cleaning tool or broken ring, clean the pis-
ton ring grooves.
(c) Using solvent and a brush, thoroughly clean the piston.
NOTICE:
Do not use a wire brush.
4. INSPECT PISTON AND CONNECTING ROD
(a) Inspect the piston oil clearance.
HINT:
There are 3 sizes of the standard piston diameter, marked º1º,
º2º and º3º accordingly. The mark is stamped on the piston top.
(1) Using a micrometer, measure the piston diameter at
right angles to the piston pin center line, 30.75 mm
(1.2106 in.) from the piston head.
Piston diameter:
