Cylinder Head Rocker Arm and Shaft Inspection
  1. Measure the inside diameter of the rocker arm, and check it for an out-of-round condition.

    Rocker Arm-to-Shaft Clearance

    Intake:
    Standard (New):
    0.019−0.050 mm (0.0007−0.0020 in.)
    Service Limit:
    0.08 mm (0.003 in.)
    Exhaust:
    Standard (New):
    0.019−0.050 mm (0.0007−0.0020 in.)
    Service Limit:
    0.08 mm (0.003 in.)

  1. Repeat for all rockers and shaft. If the clearance is beyond the service limit, replace the rocker shaft and all out of service limit rocker arms. If any VTEC rocker arm needs replacement, replace the rocker arms as an assembly.
