Honda Accord: Valve Clearance Adjustment
Special Tools Required
. Locknut Wrench 07MAA-PR70120
. Adjuster 07MAA-PR70110
NOTE: Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) and monitor the engine coolant temperature (ECT) sensor 1 with the HDS. Adjust the valve clearance only when the ECT sensor 1 temperature is less than 100 Р’В°F (38 Р’В°C).
1. Remove the cylinder head cover (see page 6-73).
2. Set the No. 1 piston at top dead center (TDC). The punch mark (A) on the variable valve timing control (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.
3. Select the correct feeler gauge for the valve clearance you are going to check.
Valve Clearance
Intake: 0.21 - 0 . 2 5 mm (0.008-0.010 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, 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 the adjuster, and turn the adjusting screw 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
Intake:
7 x 0.75 mm
14 N-m (1.4 kgf-m, 10 Ibfft) Apply new engine oil to the nut threads.
Exhaust:
7 x 0.75 mm
14 N-m (1.4 kgf-m, 10 Ibfft)
Apply new engine oil to the nut threads.
7. Rotate the crankshaft 180 Р’В° clockwise (camshaft pulley turns 90 Р’В°).
8. Check and, if necessary, adjust the valve clearance on the No. 3 cylinder.
9. Rotate the crankshaft 180 Р’В° clockwise (camshaft pulley turns 90 Р’В°).
10. Check and, if necessary, adjust the valve clearance on the No. 4 cylinder.
11. Rotate the crankshaft 180 Р’В° clockwise (camshaft pulley turns 90 Р’В°).
12. Check and, if necessary, adjust the valve clearance on the No. 2 cylinder.
13. Install the cylinder head cover (see page 6-74).
VTC Actuator Inspection
1. Remove the cam chain (see page 6-62).
2. Loosen the rocker arm adjusting screws (see step 2 on
page 6-81).
3. Remove the camshaft holder (see step 3 on page
6-81).
4. Remove the intake c ...
