CAUTION: Adjustment of valve clearance should be performed while engine is cold.





1) Measure all valve clearances.

NOTE: Record each valve clearance after it has been measured.

2) Remove the camshaft.
3) Remove the valve lifter.





4) Measure the thickness of valve lifter with a micrometer.
5) Based on the measured valve clearance and valve lifter thickness, obtain the correct amount of shims from the following table.
6) Set the correct amount of shims to the valve lifter.











7) Inspect all valves for clearance again at this stage. If the valve clearance is not correct, repeat the procedure over again from the first step.
8) After inspection, install the related parts in the reverse order of removal.
