Cylinder Head
NOTE:
l Do not reuse valve guide once disassembled.
Install new valve guide (Oversize).
l Intake and exhaust valve guides are identical.
1) Install new valve guide into cylinder head.
a) Before installing new valve guide into
cylinder head, ream guide hole with 12 mm
reamer (Special tool) to remove burrs, mak-
ing sure that guide hole diameter after
reaming comes within specified range.
Valve guide hole12.030 - 12.048 mm

b) Install valve guide to cylinder head.
Heat cylinder head uniformly at a tempe-
rature 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.
Refer to Fig. 3-6-27.
Drive in new valve guide until valve guide
installer(Special tool) contacts cylinder head.
After installation, make sure that valve
guide protrudes by 14 mm from cylinder
head (Fig. 3-6-27).

[ VSV (Vacuum Switching Valve)]
1) Disconnect VSV vacuum hoses from 3 way
joint and secondary actuator and while
blowing either hose, check that air doesn’t
come out of the other hose.
2) Turn on ignition switch and depress accelera-
tor pedal fully. 5 or 6 seconds later, while
blowing either vacuum hose, check that air
comes out of the other hose.

Idle Speed Adjustment
NOTE:
Before starting engine, place transmission gear
shift lever in “Neutral”, and set parking brake
and block drive wheels.
Before idle speed check and adjustment, make
sure of the following.
l Lead wires and hoses of engine emission
control systems are connected securely.
l Accelerator cable has some play, that is, it is
not tight.
l All vacuum hoses are connected securely.
l Fuel level should be within round mark at the
center of level gauge.
l Valve lash is checked and adjusted according
to the maintenance schedule.
l Air cleaner has been properly installed and is
in good condition.
l All accessories (wipers, heater, lights, etc) are
out of service.
l Ignition timing is within specification.
l Idle up actuator is not operating when engine
is running at idle speed.
NOTE:
In areas above 4,00Ofeet( 1,220m) elevation
(high altitude), idle up system will be normally
in operation. Do not attempt to adjust the idle
speed.
After above items are all confirmed, adjust idle
speed as follows.
1) Warm up engine to normal operating tempe-
rature.
2) Check to ensure that idle speed is within
750 - 850 r/min (rpm).
3) If idle speed is not within specified range,
adjust by turning idle speed adjusting screw.
If idle speed can not be adjusted to the speci-
fication by turning the adjusting screw, it can
be due to faulty return of throttle valve or
some other reason. Determine cause and
repair, and then adjust idle speed to specifica-
tion.
