NOTE: Connect the HDS to the DLC and monitor ECT SENSOR 1 with the HDS. Adjust the valve clearance only when the engine coolant temperature is less than 100 °F (38 °C).
Turn the crankshaft to align No. 1 position at top dead center (TDC); the white mark (A) on the crankshaft pulley lines up with the pointer (B) on the cam chain case.
2.
Set the No. 1 piston at top dead center (TDC). The "UP" mark (A) on VTC actuator A should be at the top and align the TDC marks (B) on VTC actuator A and VTC actuator B.
3.
Select the correct feeler gauge for the valve clearance you are going to check.
Valve Clearance
Intake:
0.21?0.25 mm (0.009 in)
Exhaust:
0.25?0.29 mm (0.010?0.011 in)
4.
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.
5.
If you feel too much or too little drag, loosen the locknut with the locknut wrench, and turn the adjusting screw with the adjuster until the drag on the feeler gauge is correct.
6.
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)
Apply new engine oil to the nut threads.
7.
Rotate the crankshaft clockwise. The "3" mark (A) on VTC actuator A should be at the top.
8.
Check and, if necessary, adjust the valve clearance on the No. 3 cylinder.
9.
Rotate the crankshaft clockwise. The "4" mark (A) on VTC actuator A should be at the top.
10.
Check and, if necessary, adjust the valve clearance on the No. 4 cylinder.
11.
Rotate the crankshaft clockwise. The "2" mark (A) on VTC actuator A should be at the top.
12.
Check and, if necessary, adjust the valve clearance on the No. 2 cylinder.
