8. Valve Clearance
A: INSPECTION
Inspection and adjustment of valve clearance
should be performed while engine is cold.
1) Set the vehicle on a lift.
2) Remove the collector cover.
3) Disconnect the ground cable from battery.
4) Lift-up the vehicle.
5) Remove the under cover.
6) Lower the vehicle.
7) When inspecting RH side cylinders:
(1) Remove the air intake duct and air cleaner
case. take Duct.> Air Cleaner Case.>
(2) Remove the fuel tank protector (RH).
(3) Disconnect the connector of oil pressure
switch.
(4) Remove the ignition coil. IG(H6DO)-7, REMOVAL, Ignition Coil & Ignitor
Assembly.>
(5) Remove the rocker cover (RH).
8) When inspecting LH side cylinders:
(1) Disconnect the battery cable, and then re-
move the battery and battery carrier.
(2) Disconnect the PCV hose and blow-by hose
from rocker cover (LH).
(3) Remove the fuel pipe protector (LH).
(4) Remove the ignition coil. IG(H6DO)-7, REMOVAL, Ignition Coil & Ignitor
Assembly.>
(5) Remove the rocker cover (LH).
9) Turn the crankshaft clockwise until the cam is
set to position shown in the figure.

10) Measure the clearance of intake valve and ex-
haust valve using thickness gauge (A).
NOTE:
•Measure it within the range of ±30° from speci-
fied position shown in the figure.
•Measure it in low lift cam for intake side.
•Insert a thickness gauge in a direction as hori-
zontal as possible with respect to the valve lifter.
Valve clearance
Intake:
0.20 +0.04 –0.06 mm (0.0079 +0.0016 –0.0024 in)
Exhaust:
0.35±0.05 mm (0.0138±0.0020 in)
•If the measured value is not within specification,
take notes of the value in order to adjust the valve
clearance later on.
11) If necessary, adjust the valve clearance. to ME(H6DO)-28, ADJUSTMENT, Valve Clear-
ance.>
12) Further turn the crank pulley clockwise and
then measure the valve clearances again.
13) After inspection, install the related parts in the
reverse order of removal.
B: ADJUSTMENT
1. INTAKE SIDE
CAUTION:
•Adjustment of valve clearance should be per-
formed while engine is cold.
•Do not wear gloves during removal and in-
stallation of valve lifter.
•Do not use the valve lifter which got high im-
pact due to drop etc.
•When installing the valve lifter, align the anti-
rotation of valve lifter with groove on cylinder
head, and then insert the valve lifter.
1) Measure all the valve clearances.
Clearance.>
NOTE:
Record each valve clearance after measurement.
2) Remove the camshaft. REMOVAL, Camshaft.>
3) Remove the valve lifter.
4) Remove the shim from valve lifter.
5) Check the thickness of the shim from the mark-
ings on the side of the shim that was removed.
6) Select a shim of suitable thickness from the fol-
lowing table using the measured valve clearance
and shim thickness.
