4) Connect special tool (Vacuum gauge) to intake manifold.
Special tool
(A) : 09915-67310
5) Run engine at specified idle speed and read vacuum gauge.
Vacuum should be within specification.

: 59 – 73 kPa (45 – 55 cmHg, 17.7 – 21.6 inHg)
at specified idle speed
6) After checking, disconnect special tool (Vacuum gauge) from
intake manifold.
7) Install cap to intake manifold.
OIL PRESSURE CHECK
Oil level in oil pan
If oil level is low, add oil up to Full level mark (hole) on oil
level gauge.
Oil quality
If oil is discolored, or deteriorated, change it.
For particular oil to be used referring to the table in Section
0B.
Oil leaks
If leak is found, repair it.
1) Disconnect oil pressure switch coupler (1) and remove oil
pressure switch (2) from cylinder block.
NOTE:
Prior to checking oil pressure, check the following items.
1. Full level mark (hole)
2. Low level mark (hole)

2) Install special tools (Oil pressure gauge) to vacated threaded
hole.
Special tool
(A) : 09915-77310
(B) : 09915-78211
3) Start engine and warm it up to normal operating tempera-
ture.
4) After warming up, raise engine speed to 4,000 rpm and mea-
sure oil pressure.
Oil pressure specification
: 280 – 430 kPa (2.8 – 4.3 kg/cm
2, 39.8 – 61.1 psi)
at 4,000 rpm
5) Stop engine and remove oil pressure gauge and attachment.
6) Before reinstalling oil pressure switch (2), be sure to wrap its
screw threads with sealing tape (1) and tighten switch to
specified torque.
Tightening torque
Oil pressure switch (a) : 14 N·m (1.4 kg-m, 10.5 lb-ft)
7) Start engine and check oil pressure switch for oil leakage.
If oil leakage is found, repair it.
8) Connect oil pressure switch coupler (1).
NOTE:
Be sure to place transmission gear shift lever in “Neu-
tral” (shift selector lever to “P” range for A/T model), and
set parking brake and block drive wheels.
NOTE:

VALVE LASH (CLEARANCE)
INSPECTION
1) Remove negative cable at battery.
2) Remove cylinder head cover referring to “CYLINDER HEAD
COVER”.
3) Remove right side engine cover if necessary.
4) Using 17 mm wrench, turn crankshaft pulley (1) clockwise
until cam lobes (2) become perpendicular to shim faces (3)
at valves “1” and “7” as shown in figure.
5) Check valve lashes with thickness gauge (4) according to
the following procedure.
a) Check valve lashes at valves “1” and “7”.
b) Turn camshafts by 90° (by turning crankshaft with wrench).
c) Make sure that cam lobes are perpendicular to shim faces
at valves to be checked (in this case, “3” and “8”), if not,
adjust it by turning crankshaft. Check valve lashes.
d) In the same manner as b) – c), check valve lashes at valves
“4” and “6”.
e) In the same manner as b) – c) again, check valve lashes at
valves “2” and “5”.
Valve clearance specification
If valve lash is out of specification, record valve lash and adjust it
to specification by replacing shim.
REPLACEMENT OF SHIM
1) Close the valve whose shim (2) is to be replaced by turning
crankshaft, then turn tappet (3) till its cut section (1) faces
inside as shown in figure.
2) Lift down the it valve by turning crankshaft to 180°.
3) Hold tappet at that position using special tool as follows.
a) Remove its housing bolts.When cold
(Coolant temperature
is 15 – 25°C
(59 – 77°F))When hot
(Coolant temperature
is 60 – 68°C
(140 – 154°F))
Intake 0.18 – 0.22 mm
(0.007 – 0.009 in.)0.21 – 0.27 mm
(0.008 – 0.011 in.)

(0.011 – 0.013 in.)0.30 – 0.36 mm
(0.012 – 0.014 in.)

b) Check housing No. and select special tool corresponding to
housing No., referring to “special tool selection table”.

c) Hold down the tappet so as not to hang to the shim with
special tool by installing it on camshaft housing with hous-
ing bolt (1) to specified torque.

(a) : 8 N·m (0.8 kg-m, 6.0 lb-ft)
4) Turn camshaft by approximately 90° clockwise and remove
shim (3).
5) Using a micrometer (2), measure the thickness of the
removed shim (1), and determine replacement shim by cal-
culating the thickness of new shim with the following formula
and table.
Intake side:
A = B + (C – 0.20 mm (0.008 in.))
Exhaust side:
A = B + (C – 0.30 mm (0.012 in.))

For example of intake side :
When thickness of removed shim is 2.40 mm (0.095 in.), and
measured valve clearance is 0.45 mm (0.018 in.).
A = 2.40 mm (0.094 in.) + (0.45 mm (0.018 in.) – 0.20 mm (0.008
in.)) = 2.65 mm (0.104 in.)
Calculated thickness of new shim = 2.65 mm (0.104 in.)
6) Select new shim No. (1) with a thickness as close as possi-
ble to calculated valve.
Available new shims No.
7) Install new shim facing shim No. side with tappet.
8) Lift valve by turning crankshaft counterclockwise (in opposite
direction against above Step 4) and remove special tool.
