Valve inspection set ( 07LAJ-PR30102)
| 1. | Start the engine, and let it run for 5 minutes, then turn OFF the ignition switch. |
| 2. | Remove the cylinder head cover. |
| 3. | Set the No. 1 piston at top dead center (TDC). |
| 4. | Move the intake secondary rocker arm A for the No. 1 cylinder. The secondary rocker arm A should move independently of the secondary rocker arm B.
|
| 5. | Repeat 4 on the remaining intake secondary rocker arms with each piston at TDC. When all the secondary rocker arms pass the test, go to 6. |
| 6. | Check that the air pressure on the shop air compressor gauge indicates over 400 kPa (4 kgf/cm2, 57 psi). |
| 7. | Inspect the valve clearance. |
| 8. | Install the VTEC adapter (A) to the inspection hole, then connect the valve inspection set (B).
|
| 9. | Loosen the valve on the regulator, and apply the specified air pressure.
|
| 10. | With the specified air pressure applied, move the intake secondary rocker arm A for the No. 1 cylinder. The secondary rocker arm A and secondary rocker arm B should move together. If the intake secondary rocker arm A does not move, remove the secondary rocker arms as an assembly, and check that the pistons in the secondary rocker arms move smoothly. If any rocker arm needs replacing, replace the secondary rocker arms as an assembly, and retest.
