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 page 6-36).
3. Set the No. 1 piston at top dead center (TDC) (see step 5 on page 6-18).
4. Move the intake primary rocker arm (A) for the No. 1 cylinder. The primary rocker arm should
move 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 do not move independently, remove the primary and
secondary rocker arms as an assembly and check
that the pistons in the secondary and primary
rocker arms move smoothly. If any rocker arm
needs replacing, replace the primary and
secondary rocker arms as an assembly, then
retest. 5. Repeat step 4 on the remaining intake primary
rockerarmswitheachpistonatTDC.Whenallthe
primary rocker arms pass the test, go to step 6.
6. Check that the air pressure on the shop air compressor gauge indicates over 400 kPa
(4 kgf/cm , 57 psi).
7. Inspect the valve clearance (see page 6-12).
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 the air pressure regulator (E).
11. Loosen the valve on the air pressure regulator, and apply the specified air pressure.
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.
