Valve Clearance: Adjustments

ADJUSTMENT

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 camshaft.
3) Remove the valve lifter.
4) Measure the thickness of valve lifter using micrometer.





5) Select and install a valve lifter of suitable thickness from the following table, based on the measured valve clearance and valve lifter thickness.

NOTE: Use new valve lifters.











6) Install the camshaft.
7) Install the cam sprocket.
8) Install the timing belt.
9) Measure all valves for valve clearance again at this time. If the valve clearance is not within the adjustment value, repeat the procedure over again from the first step.
Valve clearance (adjustment value):
Intake: 0.20+0.01 -0.03 mm (0.0079 + 0.0004-0.0012 in)
Exhaust: 0.35±0.02 mm (0.0138±0.0008 in)
10) After measuring, install the related parts in the reverse order of removal.

NOTE: Use a new rocker cover gasket.
