Valve Clearance: Adjustments
Valve ClearanceADJUSTMENT
INTAKE SIDE
CAUTION:
If engine oil is spilt onto the exhaust pipe, wipe it off with cloth to avoid emission of smoke or causing a fire.
NOTE:
Adjustment of valve clearance should be performed while engine is cold.
1) Measure all the valve clearances.
NOTE:
Record each valve clearance after measurement.
2) Remove the timing chain assembly.
3) Remove the cam sprocket.
4) Remove the camshaft.
5) Remove the valve lifter.
6) Measure the thickness of valve lifter using micrometer.
7) Select a valve lifter of suitable thickness using the measured valve clearance and valve lifter thickness, and install it.
NOTE:
Use a new valve lifter.
8) Install the camshaft.
9) Install the cam sprocket.
10) Install the timing chain assembly.
11) Measure all valve clearance again at this time. If the valve clearance is not correct, repeat the procedure over again from the first step.
Valve clearance (adjustment value):
0.20 [+0.04/-0.06] mm (0.0079 [+0.0016/-0.0024] in)
12) After measuring, install the related parts in the reverse order of removal.
NOTE:
Use a new rocker cover gasket.
EXHAUST SIDE
CAUTION:
If engine oil is spilt onto the exhaust pipe, wipe it off with cloth to avoid emission of smoke or causing a fire.

7) Install the cam sprocket.
8) Install the timing chain assembly.
9) Measure all valve clearance again at this time. If the valve clearance is not correct, repeat the procedure over again from the first step.
Valve clearance (adjustment value):
0.35 ± 0.05 mm (0.0138 ± 0.0020 in)
10) After measuring, install the related parts in the reverse order of removal.
NOTE:
Use a new rocker cover gasket.
