Oil Pump Strainer
Install oil pump strainer to oil pump.
Bearing in mind that “O” ring is often forgotten and left out
in reassembly. Absence of this ring defeats the purpose
served by the strainer.
Oil Pan
1) Clean mating surfaces of oil pan and cylinder block.
Remove oil, old sealant, and dusts from mating surfaces.
After cleaning, apply silicon type sealant to oil pan mating
surface continuously.
2) After fitting oil pan to block, run in securing bolts and
start tightening at the center: move wrench outward,
tightening one bolt at a time. Tighten bolts to specified
torque.
Tightening torque for oil pan bolt
9–12 N–m
0.9–1.2 kg–m
7.0–8.5 lb–ft
Cylinder Head
NOTE:
Do not reuse valve guide once disassembled.
Install new (oversize) valve guide.
Intake and exhaust valve guides are identical.
Valve guide oversize 0.03 mm (0.0012 in.)
Valve guide protrusion
(Intake and exhaust)
13 mm (0.51 in.)
1) Install new valve guide into cylinder head.
a) Before installing new valve guide into cylinder head,
ream guide hole with 10.5 mm reamer (Special tool) to
remove burrs, making sure that guide hole diameter after
reaming comes within specified range.
Valve guide hole diameter
(Intake & Exhaust)
10.530–10.545 mm
(0.4146–0.4151 in.)
b) Install valve guide to cylinder head.
Heat cylinder head uniformly at temperature of 80 to 100°
C (176 to 212° F), using care not to distort head, and
drive new valve guide into hole with special tools.
Drive in new valve guide until valve guide installer (Spe-
cial tool) contacts cylinder head. After Installation, make
sure that valve guide protrudes by 13 mm from cylinder
head.
c) Ream valve guide bore with 5 mm reamer (Special
tool). After reaming, clean bore.
