Honda CR-V: Valve Clearance Adjustment

Special Tools Required

NOTE: Adjust the valves only when the cylinder head temperature is less than 100 ºF (38 ºC).

1. Remove the cylinder head cover.

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 exhaust camshaft sprocket.

3. Select the correct thickness feeler gauge for the valves you're going to check.

Valve Clearance

Intake: 0.21-0.25 mm (0.008-0.010 in.)
Exhaust: 0.28-0.32 mm (0.011-0.013 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 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
20 N*m (2.0 kgf*m, 14 Ibf*tt)
Apply engine oil to the nut threads.

Exhaust:
7x 0.75mm
14 N*m (1.4 kgf*m, 10 Ibf*tt)
Apply engine oil to the nut threads.

7. Rotate the crankshaft 180 º clockwise (camshaft pulley turns 90 º).

12. Check and, if necessary, adjust the valve clearance on No.2 cylinder.

13. Install the cylinder head cover.
