compression.



Damaged or worn valves and seats



Damaged cylinder head gasket



Damaged or worn piston rings



Damaged or worn piston and cylinder bore

13. Remove the compression gauge from the spark plug hole.

14. Install the four spark plugs (see SPARK PLUG INSPECTION ).

15. Install the four ignition coils (see IGNITION COIL REMOVAL/INSTALLATION ).

16. Select the ECM/PCM reset (see IF THE MIL DID NOT STAY ON ) to cancel ALL INJECTORS OFF

FUNCTION on the HDS.

VTEC ROCKER ARM TEST

Special Tools Required



Air pressure regulator 07AAJ-PNAA101



VTEC air adapter 07ZAJ-PNAA101



VTEC air stopper 07ZAJ-PNAA200



Air joint adapter 07ZAJ-PNAA300

1. Start the engine and let it run for 5 minutes, then turn the ignition switch OFF.

2. Remove the cylinder head cover (see CYLINDER HEAD COVER REMOVAL ).

3. Set the No. 1 piston at top dead center (TDC) (see step 4 ).

4. Verify that the intake primary rocker arm (A) moves independently of the intake secondary rocker arm

(B).



If the intake primary rocker arm moves freely, go to step 5.



If the intake primary rocker arm does not move, remove the primary and secondary rocker arms as
an assembly and check that the pistons in the secondary and primary rocker arms move smoothly
(see ROCKER ARM AND SHAFT INSPECTION ). If any rocker arm needs replacing, replace
the primary and secondary rocker arms as an assembly, and test.

5. Repeat step 4 on the remaining intake primary rocker arms with each piston at TDC. When all the

primary rocker arms pass the test, go to step 6.

6. Inspect the valve clearance (see VALVE CLEARANCE ADJUSTMENT ).

7. Check that the air pressure on the shop air compressor gauge indicates over 400 kPa (4.0 kgf/cm

2

, 57

psi).

8. Remove the sealing bolt (A) from the relief hole, and install the VTEC air stopper (B).

9. Remove the No. 2 and No. 3 camshaft holder bolts, and install the VTEC air adapters (C) finger-tight.

10. Connect the air joint adapter (D) and air pressure regulator (E).

11. Loosen the valve on the regulator, and apply the specified air pressure.

Specified Air Pressure:

290 kPa (3.0 kgf/cm

2

, 42 psi)

12. 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 secondary rocker arm does not move, remove the primary and secondary rocker arms as an

NOTE:

If the rocker arm piston does not move after applying air pressure, move
the primary or secondary rocker arm up and down manually by rotating
the crankshaft clockwise.

assembly, and check that the pistons in the primary and secondary rocker arms move smoothly (see
ROCKER ARM AND SHAFT INSPECTION ). If any rocker arm needs replacing, replace the primary
and secondary rocker arms as an assembly, and test.

13. Repeat steps 11 and 12 for the remaining cylinders. Be sure to set the cylinder's piston at TDC before

beginning work.

14. Remove the VTEC air stopper and VTEC air adapters.

15. Torque the camshaft holder mounting bolts to 22 N.m (2.2 kgf.m, 16 lbf.ft).

16. Torque the sealing bolt to 20 N.m (2.0 kgf.m, 15 lbf.ft).

17. Install the cylinder head cover (see CYLINDER HEAD COVER INSTALLATION ).

VTC ACTUATOR INSPECTION

1. Remove the cam chain (see CAM CHAIN REMOVAL ).

2. Loosen the rocker arm adjusting screws (see step 2 ).

3. Remove the camshaft holders (see step 3 ).

4. Remove the intake camshaft.

5. Check that the variable valve timing control (VTC) actuator is locked by turning the VTC actuator

counterclockwise. If not locked, turn the VTC actuator clockwise until it stops, then recheck it. If it is still
not locked, replace the VTC actuator.

6. Seal the advance holes (A) and retard holes (B) in the No. 1 camshaft journal with tape.

7. Punch a hole in the tape over one of the advance holes.

8. Apply air to the advance hole to release the lock.

9. Check that the VTC actuator moves smoothly. If the VTC actuator does not move smoothly, replace the

VTC actuator.
