Valve Lash (Clearance) Adjustment
Before servicing the vehicle, refer to the Precautions Section.
Check the engine oil. Change or adjust level as required.
Idle the engine for one to three minutes, to allow it to warm up.
Repeat the operation as indicated in the illustration. At a no load condition check for abnormal noise.
Usually the abnormal noise is eliminated after repetition of the operation ten to thirty times. If no change is observed, suspect that the abnormal noise is due to other factors.

After elimination of the abnormal noise, repeat the operation (in the illustration) five more times.
Run the engine at idle for one to three minutes to be sure the abnormal noise has been eliminated.
