Valve Clearance
MECHANICAL
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.

±
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. <Ref.
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.

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 valve lifters that were dropped or
otherwise exposed to strong impacts.
• 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.
<Ref. to ME(H6DO)-27, INSPECTION, Valve
Clearance.>
NOTE:
Record each valve clearance after measurement.
2) Remove the camshaft. <Ref. to ME(H6DO)-53,
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.
