===''ROCKER ARM TEST''===
1. Remove the [[CylinderHeadS2k cylinder head cover]].
3. Move the secondary rocker arm for No. 1 cylinder. The secondary rocker arm should move independently of the mid rocker arm.
6. Remove the No. 3 and No. 4 camshaft holder bolts, and install the VTEC air adapters finger-tight.
7. Install the gauge joint adapter to the inspection hole.
8. Connect the air joint adapter to the VTEC air adapters.
9. Connect the air pressure regulator to the air joint adapter.
10. With the specified air pressure applied and the piston at TDC, move the secondary rocker arm. The mid rocker arm, primary rocker arm, and secondary rocker arm should move together. If the three rocker arms do not move together, replace the rocker arms as a set.
13. Install the [[CylinderHeadS2k cylinder head cover]].
<<{{source2}}<< ===''ROCKER ARM AND SHAFT INSPECTION''===
1. Remove the dipstick, positive crankcase ventilation (PCV) hose and breather hose (see step 18 on [[CylinderHeadS2k Cylinder Head Removal]] ).
2. Remove the ignition coil cover, then remove the ignition coils (see step 19 on [[CylinderHeadS2k Cylinder Head Removal]] ).
3. Remove the cylinder head cover (see step 22 on [[CylinderHeadS2k Cylinder Head Removal]] ).
4. Loosen the rocker arm adjusting screws (see step 28 on [[CylinderHeadS2k Cylinder Head Removal]] ).
6. Insert the bolts into the rocker shaft holder, then remove the rocker arm assembly (see step 30 on [[CylinderHeadS2k Cylinder Head Removal]] ).
8. Zero the gauge to the shaft diameter.
11. Inspect the rocker arm pistons. Push each piston manually. If it does not move smoothly, replace the rocker arm assembly.
~-**When reassembling the primary rocker arm, carefully apply air pressure to its oil passage.

9. Measure the inside diameter of the rocker arm, and check it for an out-of-round condition.
~-Rocker Arm-to-Shaft Clearance:
~-Standard (New): 0.021-0.041 mm (0.0008-0.0016 in.)
~-Service Limit: 0.07 mm (0.003 in.)
{{image url="http://www.garage411.com/images/Honda/Ap1/Engine/rockerarms126.gif" title="text" alt="text"}}
10. Repeat for all rocker arms and both shafts. If the clearance is over the limit, replace the rocker shaft and all overtolerance rocker arms. If any rocker arm needs replacement, replace all three rocker arms in that set (primary, mid, and secondary).
>>{{sourcebigbox}}>> 11. Inspect the rocker arm pistons (A). Push each piston manually. If it does not move smoothly, replace the rocker arm assembly.
~-**When reassembling the primary rocker arm (B), carefully apply air pressure to its oil passage.
~-Apply new engine oil to the pistons when reassembling.**
