• Measurement of clearance of #1 cylinder intake
valve and #3 cylinder exhaust valve
• Measurement of clearance of #2 cylinder ex-
haust valve and #3 cylinder intake valve
• Measurement of clearance of #2 cylinder intake
valve and #4 cylinder exhaust valve
• Measurement of clearance of #1 cylinder ex-
haust valve and #4 cylinder intake valve
12) Measure the clearance of intake valve and ex-
haust valve using thickness gauge (A).
NOTE:
• Insert a thickness gauge in a direction as hori-
zontal as possible with respect to the valve lifter.
• Lift up the vehicle, and then measure the ex-
haust valve clearances.
• If the measured value is not within the inspection
value, take notes of the value in order to adjust the
valve clearance later on.
Valve clearance (inspection value):
Intake
0.20
+0.04
–0.06
mm (0.0079
+0.0016
–0.0024
in)
Exhaust
0.35
r
0.05 mm (0.0138
r
0.0020 in)
13) If necessary, adjust the valve clearance. <Ref.

ance.>
14) After inspection, install the related parts in the
reverse order of removal.
NOTE:
• Use a new rocker cover gasket.
• Use a new clamp for the PCV hose clamp, fit the
cut out in the ST with the protrusion on the clamp as
