CR-V Models
1. Clearances are checked on a cold engine (temperature not higher than 38°C).
2. The piston of the cylinder, the valve clearances of which are being checked, must be at TDC of the compression stroke.
3. Remove the cylinder head cover and upper camshaft belt cover.
4. Set the piston of the 1st cylinder to TDC of the compression stroke by turning the crankshaft counterclockwise. The white mark on the crankshaft pulley should align with the pointer on the camshaft belt cover. The UP marks on the camshaft sprockets should be facing up, and the TDC marks should be aligned with the marks on the split plane of the cylinder head cover.
5. Check the intake valve clearances with a feeler gauge inserted between the rocker arm and the camshaft cam. To do this, first insert a 0.08 mm feeler gauge. If the feeler gauge does not pass, the gap should be adjusted. If this probe passes, then lay a 0.15 mm probe. If this probe does not pass in the gap, then the gap is normal, otherwise the gap should be adjusted.
6. For the CR-V model, the normal intake valve clearance is 0.08-0.12 mm.
7. To adjust the intake valves, do the following. Loosen the lock nut and, by turning the screw, increase the gap so that a 0.1 mm feeler gauge can be inserted. Holding the lock nut, tighten the screw until you feel slight resistance; the feeler gauge should pass through with a slight effort. While holding the screw, tighten the lock nut and check the clearance.
8. To adjust the intake valves, do the following. Loosen the lock nut and, by turning the screw, increase the gap so that a 0.1 mm feeler gauge can be inserted. Holding the lock nut, tighten the screw until you feel slight resistance; the feeler gauge should pass through with a slight effort. While holding the screw, tighten the lock nut and check the clearance.
9. Check the clearances of the exhaust valves. To do this, place a 0.15 mm feeler gauge between the rocker arm and the camshaft cam. If the feeler gauge does not fit, the gap should be adjusted. If this probe passes, then lay a 0.22 mm probe. If this probe does not pass in the gap, then the gap is normal, otherwise the gap should be adjusted.
10. For the CR-V model, the normal clearance for the exhaust valves is 0.16-0.20 mm.
11. To adjust the exhaust valves, proceed as follows. Loosen the lock nut and, by turning the screw, increase the gap so that a 0.18 mm feeler gauge can be inserted. While holding the lock nut, tighten the screw until you feel slight resistance; the feeler gauge should pass through with a slight effort. While holding the screw, tighten the lock nut and check the clearance.
12. Repeat the procedure for the remaining valves of this cylinder.
13. Turning the crankshaft counterclockwise, check and adjust the clearances in the valves of the 3rd cylinder, then in the valves of the 4th and, finally, in the valves of the 2nd cylinder.
14. When the piston of the 3rd cylinder is set at TDC of the compression stroke, the UP marks on the camshaft sprockets should be facing left horizontally.
15. When the piston of the 4th cylinder is set at TDC of the compression stroke, the UP marks on the camshaft sprockets should be facing down, and the TDC marks should be aligned with the split plane of the cylinder head cover.
16. When the piston of the 2nd cylinder is set to TDC of the compression stroke, the UP marks on the camshaft sprockets should be facing right horizontally.
17. After adjusting the valves, check the tightening of the crankshaft pulley bolt; if necessary, tighten the bolt to a torque of 117 Nm.

18. Install the removed parts. Install the cylinder head cover using sealant.
Odyssey with 4-cylinder engine
1. Clearances are checked on a cold engine (temperature not higher than 38°C).
2. The piston of the cylinder, the valve clearances of which are being checked, must be at TDC of the compression stroke.
3. Remove the cylinder head cover and upper camshaft belt cover.
4. Set the piston of the 1st cylinder to TDC of the compression stroke by turning the crankshaft counterclockwise. The white mark on the crankshaft pulley should align with the pointer on the camshaft belt cover. The UP marks on the camshaft sprockets must face up.
5. Check the intake valve clearances with a feeler gauge inserted between the rocker arm and the valve stem. The clearance for the intake valves is 0.26 mm, for the exhaust valves - 0.30 mm.
6. Check the clearance for the intake valves in the following order. Place a 0.24 mm feeler gauge between the rocker arm and the valve stem. If the feeler gauge does not fit, the gap should be adjusted. If this probe passes, then lay a 0.28 mm probe. If this probe does not pass in the gap, then the gap is normal, otherwise the gap should be adjusted.
7. To adjust the intake valves, do the following. Loosen the lock nut and, by turning the screw, increase the gap so that a 0.26 mm feeler gauge can be inserted. While holding the lock nut, tighten the screw until you feel slight resistance; the feeler gauge should pass through with a slight effort. While holding the screw, tighten the lock nut and check the clearance.
8. Check the clearance for the exhaust valves in the following order. First, place a 0.28 mm feeler gauge between the rocker arm and the valve stem. If the feeler gauge does not fit, the gap should be adjusted. If this probe passes, then lay a 0.33 mm probe. If this probe does not pass in the gap, then the gap is normal, otherwise the gap should be adjusted.
9. To adjust the exhaust valves, proceed as follows. Loosen the lock nut and, by turning the screw, increase the gap so that a 0.30 mm feeler gauge can be inserted. While holding the lock nut, tighten the screw until you feel slight resistance; the feeler gauge should pass through with a slight effort. While holding the screw, tighten the lock nut and check the clearance.
10. Check the clearances of the exhaust valves.
11. Repeat the procedure for the remaining valves of this cylinder.
13. Turning the crankshaft counterclockwise, check and adjust the clearances in the valves of the 3rd cylinder, then in the valves of the 4th and, finally, in the valves of the 2nd cylinder.
14. When the piston of the 3rd cylinder is set at TDC of the compression stroke, the UP marks on the camshaft sprockets should be facing left horizontally.
15. When the piston of the 4th cylinder is set at TDC of the compression stroke, the UP marks on the camshaft sprockets should be facing down, and the TDC marks should be aligned with the split plane of the cylinder head cover.
16. When the piston of the 2nd cylinder is set to TDC of the compression stroke, the UP marks on the camshaft sprockets should be facing right horizontally.
17. After adjusting the valves, check the tightening of the crankshaft pulley bolt; if necessary, tighten the bolt to a torque of 245 Nm.
