33. INSTALL CAMSHAFT
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while being installed. If the
camshaft is not kept level, the cylinder head or camshaft
may be damaged. To avoid this, the following steps must
be carried out.
(a) Apply new engine oil to the thrust portion and journal of
the camshaft.
(b) Align the timing marks (2 dot marks) of the camshaft drive
and driven gears.
(c) Place the camshaft on the cylinder head.
(d) Install the 5 bearing caps in their proper locations.
(e) Apply a light coat of engine oil to the threads of the bear-
ing cap bolts.
(f) Using several steps, tighten the 10 bearing cap bolts uni-
formly in the sequence shown in the illustration.
Torque: 16 NVm (163 kgfVcm, 12 ftVlbf)
(g) Remove the service bolt.
34. INSTALL TIMING BELT NO.3 COVER
(a) Visually check for cracks and breaks on the gasket of the
timing belt cover.
HINT:
If there is a trace of water intrusion when checking visually, re-
pair the gasket with seal packing when the crack length is within
2 to 3 cm (0.79 to 1.18 in.). Replace the gasket when the crack
length is 3 to 4 cm (1.18 to 1.57 in.) or longer.

41. INSTALL CYLINDER HEAD GASKET
(a) Place a new cylinder head gasket on the cylinder block
with the R mark upward.
NOTICE:
Remove any oil from the contact surface.
Be careful of the installing orientation.
Place the cylinder head on the gasket carefully in or-
der not to damage the gasket at the bottom part of the
head.
42. INSTALL CYLINDER HEAD SUB-ASSY
NOTICE:
The cylinder head bolts are tightened in 2 successive
steps.
(a) Apply a light coat of engine oil to the threads of the cylin-
der head bolts.
(b) Install the plate washers to the cylinder head bolts.
(c) Using several steps, install and tighten the 8 cylinder
head bolts uniformly in the sequence shown in the illustra-
tion.
Torque: 54 NVm (550 kgfVcm, 40 ftVlbf)
(d) Mark the front side of each cylinder head bolt head with
paint as shown in the illustration.
(e) Retighten the cylinder head bolts by 90in the same se-
quence as step (c).
(f) Check that each painted mark is now at a 90 angle to the
front.

17. INSPECT VALVE SEATS
(a) Apply a light coat of prussian blue (or white lead) to the
valve face.
(b) Lightly press the valve against the seat.
NOTICE:
Do not rotate the valve.
(c) Check the valve face and seat according to the following
procedure.
(1) If blue appears 360 around the face, the valve is
concentric. If not, replace the valve.
(2) If blue appears 360 around the valve seat, the
guide and face are concentric. If not, resurface the
seat.
(3) Check that the seat contact is in the middle of the
valve face with the width between 1.0 and 1.4 mm
(0.039 to 0.055 in.).
18. REPAIR VALVE SEATS
NOTICE:
Releasing the seat cutter pressure gradually helps to make
smoother valve seat faces.
(a) If the seating is too high on the valve face, use the 30 and
45 cutters to correct the seat.
(b) If the seating is too low on the valve face, use the 60 and
45 cutters to correct the seat.
(c) Lap the valve and valve seat by hand with an abrasive
compound.
(d) Recheck the valve seating position.
19. INSPECT VALVE LIFTER
(a) Using a micrometer, measure the lifter diameter.
Lifter diameter:
30.966 to 30.976 mm (1.2191 to 1.2195 in.)
