Remove the cylinder head cover
Set the No. 1 piston at top dead center (TDC). The punch mark (A) on the VTC actuator and the punch mark (B) on the exhaust camshaft sprocket should be at the top. Align the TDC marks (C) on the VTC actuator and the exhaust camshaft sprocket.
Select the correct feeler gauge for the valve clearance you are going to check.
Valve Clearance
Intake: 0.21-0.25 mm (0.009-0.009 in)
Exhaust: 0.25-0.29 mm (0.010-0.011 in)
Rear
Front
Insert the feeler gauge (A) between the adjusting screw (B) and the end of the valve stem on the No. 1 cylinder, and slide it back and forth; you should feel a slight amount of drag.
Intake
Exhaust
If you feel too much or too little drag, loosen the locknut with the locknut wrench and the adjuster, and turn the adjusting screw until the drag on the feeler gauge is correct.
Intake
Exhaust
Tighten the locknut to the specified torque, and recheck the clearance. Repeat the adjustment if necessary.
Specified Torque:
14 N·m (1.4 kgf·m, 10 lbf·ft)
