Removal
Place a rubber band around each set of rocker arms to keep them together. Remove intake and exhaust rocker shaft oil control orifices. Remove VTEC solenoid valve and sealing bolts. Screw a 12-mm bolt into end of rocker shaft. Pull bolt head to remove rocker shaft and rocker arms. Mark parts for installation reference as they are removed.
Shape of intake oil orifices are different than exhaust oil orifices. Ensure reinstallation in original locations.
Inspection
1. Push rocker arm pistons manually. If they do not move smoothly, replace rocker arm assembly. Remove lost motion assembly from cylinder head and test by pushing plunger with finger. If lost motion assembly does not move smoothly, replace assembly.
2. Measure diameter of intake and exhaust rocker shafts at first rocker location. Measure ID of rocker arms, and check for out of round condition. Repeat for all rocker arms. If out of round condition is detected, replace rocker arms. Always replace rocker arms as a set of 3.
Installation
Lubricate all components before installation. Install all components into original locations. Back off valve adjuster screws before installation. If holes in cylinder head and rocker shafts are not in line, turn shaft with 12-mm bolt threaded into end. To complete installation, reverse removal procedure.
