Special Tools Required

  1. Start the engine and let it run for 5 minutes, then turn the ignition switch to LOCK (0).
  2. Remove the cylinder head cover (see CYLINDER HEAD COVER REMOVAL  ).
  3. Rotate the crankshaft pulley clockwise. Make sure that the intake secondary rocker arm (A) and the intake primary rocker arm (B) are separated and that the intake secondary rocker arm and the intake primary rocker arm should move independently:
    • If the intake primary and secondary rocker arms move together, remove the primary and secondary rocker arms as an assembly, and check that the pistons in the primary and secondary rocker arms move smoothly. If any rocker arm needs replacing, replace the primary and secondary rocker arms as an assembly, then retest.
    • If the intake primary and secondary rocker arms move independently, go to step 4.

  4. Check that the air pressure on the shop air compressor gauge indicates over 400 kPa (4.0 kgf/cm2, 57 psi).
  5. Inspect the valve clearance (see VALVE CLEARANCE ADJUSTMENT  ).
  6. Remove the sealing bolt (A) from the relief hole, and install the VTEC air stopper (B).
  7. Remove the No. 2 and No. 3 camshaft holder bolts, and install the VTEC air adapters (C) finger-tight.

  8. Connect the air joint adapter (D) and air pressure regulator (E).
  9. Loosen the valve on the regulator, and apply the specified air pressure.

    Specified Air Pressure: 

    290 kPa (3.0 kgf/cm 2  , 42 psi) 

  10. With the specified air pressure applied, move the intake primary rocker arm (A) for the No. 1 cylinder. The primary rocker arm and secondary rocker arm (B) should move together.
    • If the intake primary and secondary rocker arms move independently, remove the primary and secondary rocker arms as an assembly, and check that the pistons in the rocker arms move smoothly. Refer to Rocker Arm and Shaft Inspection . If any rocker arm needs replacing, replace the primary and secondary rocker arms as an assembly, then retest.
    • If the primary and secondary rocker arms move together, go to step 11.

  11. Remove the air pressure regulator, the air joint adapter, the VTEC air adapters, and the VTEC air stopper.
  12. Torque the camshaft holder mounting bolts to 22 N.m (2.2 kgf.m, 16 lbf.ft).
  13. Torque the sealing bolt to 10 N.m (1.0 kgf.m, 7.4 lbf.ft).
  14. Install the cylinder head cover (see CYLINDER HEAD COVER INSTALLATION  ).
  15. Install the four spark plugs and the four ignition coils. Refer to IGNITION COIL & SPARK PLUG REMOVAL/INSTALLATION
