15) Check cylinder head upper cover gasket for
deterioration and then install it into groove of cylinder
head upper cover (1) securely.

Engine Vacuum Check
The engine vacuum that develops in the intake line is a
good indicator of the condition of the engine. The
vacuum checking procedure is as follows:
1) Warm up engine to normal operating temperature.
NOTE
After warming up engine, be sure to place
transaxle gear shift lever in "Neutral" (shift
selector lever to "P" range for A/T model),
and set parking brake and block drive
wheels.
2) Stop engine and turn off the all electric switches.
3) Remove cap (1) from intake manifold.

4) Connect special tool (Vacuum gauge) to intake
manifold side.
Special tool
(A): 09915–67311

5) Run engine at specified idle speed and read vacuum
gauge. Vacuum should be within specification.
Vacuum specification (at sea level)
59 – 73 kPa (45 – 55 cmHg, 17.7 – 21.6 in.Hg) at
specified idle speed
6) After checking, disconnect special tool (Vacuum
gauge) from intake manifold.
7) Install cap to intake manifold.

3) Remove right side engine under 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
the 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".
