• VTEC air adapter 07VAJ-P8A010A
• VTEC air stopper 070AJ-0030100
• Air pressure regulator 07AAJ-PNAA101

1. Start the engine and let it run for 5 minutes, then

turn the ignition switch OFF.

2. Remove the intake manifold (see page 9-3).

3. Remove the cylinder head covers (see page 6-25).

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

step 3 on page 6-8).

5. Push on the intake mid rocker arm (A) for the No. 1

cylinder. The mid rocker arm should move
independently of the primary rocker arm (B) and
secondary rocker arm (C).

• If the mid rocker arm moves freely, go to step 6.
• If the intake mid rocker arm does not move,

remove the mid, primary, and secondary intake
rocker arms as an assembly, then check that the
pistons in the mid and primary rocker arms move
smoothly. If any rocker arm needs replacing,
replace the mid, primary, and secondary rocker
arms as an assembly, then retest.

6. Repeat step 5 on the remaining intake mid rocker

arms with each piston at TDC. When all the mid
rocker arms pass the test, go to step 7.

7. Check that the air pressure on the shop air

compressor gauge indicates over 690 kPa
(7.0 kgf/cm , 100 psi).

8. Inspect the valve clearance (see page 6-8).

9. Remove the No. 1 and No. 6 intake rocker shaft

mounting bolts, then install the VTEC air adapter
and VTEC air stopper, and connect the air pressure
regulator as shown.

10. Loosen the valve on the air pressure regulator, and

apply the specified air pressure.

NOTE: If the synchronizing pistons do not move
after applying air pressure, move the primary or
secondary rocker arm up and down manually.

11. Make sure that the intake primary rocker arm (A)

and intake secondary rocker arm (B) are
mechanically connected by the piston and that the
mid rocker arm (C) does not move when pushed
manually. If any intake mid rocker arm moves
independently of the primary and secondary rocker
arms, replace the rocker arms as a set.

12. Remove the special tools.

13. Tighten the rocker shaft bolts to 24 N·m (2.4 kgf·m,

17 lbf·ft)

14. Install the cylinder head covers (see page 6-26).

15. Install the intake manifold (see page 9-5).

NOTE: Adjust the valves only when the cylinder head
temperature is less than 100 °F (38 °C).

1. Remove the intake manifold (see page 9-3).

2. Remove the cylinder head covers (see page 6-25).

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

Align the pointer (A) on the front upper cover with
the No. 1 piston TDC mark (B) on the front camshaft
pulley.

4. Select the correct thickness feeler gauge for the

valves you’re going to check.

5. Insert the feeler gauge (A) between the adjusting

screw and the end of the valve stem on No. 1
cylinder and slide it back and forth; you should feel
a slight amount of drag.

6. If you feel too much or too little drag, loosen the

locknut (A), and turn the adjusting screw (B) until
the drag on the feeler gauge is correct.

7. Tighten the locknut and recheck the clearance.

Repeat the adjustment, if necessary.

8. Rotate the crankshaft clockwise. Align the pointer

(A) on the front upper cover with the No. 4 piston
TDC mark (B) on the front camshaft pulley.

9. Check and, if necessary, adjust the valve clearance

on No. 4 cylinder.

10. Rotate the crankshaft clockwise. Align the pointer

(A) on the front upper cover with the No. 2 piston
TDC mark (B) on the front camshaft pulley.

11. Check and, if necessary, adjust the valve clearance

on No. 2 cylinder.

12. Rotate the crankshaft clockwise. Align the pointer

(A) on the front upper cover with the No. 5 piston
TDC mark (B) on the front camshaft pulley.

13. Check and, if necessary, adjust the valve clearance

on No. 5 cylinder.

14. Rotate the crankshaft clockwise. Align the pointer

(A) on the front upper cover with the No. 3 piston
TDC mark (B) on the front camshaft pulley.

15. Check and, if necessary, adjust the valve clearance

on No. 3 cylinder.
