14) Further turn the crank pulley clockwise and
then measure the valve clearances again.
(1) Set the arrow mark on cam sprocket to the
position shown in the figure, and measure the #2
cylinder exhaust valve and #3 cylinder intake
valve clearances.
(2) Set the arrow mark on cam sprocket to the
position shown in the figure, and measure the #2
cylinder intake valve and #4 cylinder exhaust
valve clearances.
(3) Set the arrow mark on cam sprocket to the
position shown in the figure, and measure the #1
cylinder exhaust valve and #4 cylinder intake
valve clearances.
15) After inspection, install the related parts in the
reverse order of removal.
Valve Clearance
B: ADJUSTMENT
CAUTION:
Adjustment of valve clearance should be per-
formed while engine is cold.
1) Measure all valve clearances.
<Ref. to ME(H4DOTC)-28, INSPECTION, Valve
Clearance.>
NOTE:
Record each valve clearance after measurement.
ME-00734
2) Remove the camshaft. <Ref. to ME(H4DOTC)-
56, REMOVAL, Camshaft.>
3) Remove the valve lifter.
4) Measure the thickness of valve lifter using a mi-
crometer.
ME-00735
5) Select a valve lifter of suitable thickness from the
following table using the measured valve clearance
and valve lifter thickness.
Intake valve: S = (V + T) − 0.20
Exhaust valve: S = (V + T) − 0.35
S: Valve lifter thickness required
V: Measured valve clearance
T: Valve lifter thickness to be used
