NOTE: Connect the HDS to the DLC, and monitor ECT SENSOR 1. Adjust the valve clearance only when the engine coolant temperature is less than 100 °F (38 °C).
Set the No. 1 piston at top dead center (TDC). Align the pointer (A) on the front upper cover with the No. 1 piston TDC mark (B) on the front camshaft pulley.

Select the correct feeler gauge for the valve clearance you are going to check.
Valve Clearance
Intake:
0.20?0.24 mm (0.0079?0.0094 in)
Exhaust:
0.28?0.32 mm (0.0110?0.0126 in)

4.
If you feel too much or too little drag, loosen the locknut, and turn the adjusting screw until the drag on the feeler gauge is correct.
5.
While holding the adjusting screw with the screw driver, tighten the locknut, then recheck the clearance. Repeat the adjustment, if necessary.
Specified Torque
Intake:
20 N·m (2.0 kgf·m, 15 lbf·ft)
Apply new engine oil to the nut threads.
Exhaust:
