Valve Clearance: Notes

  1. Adjust valves with engine cold. Rotate crankshaft so No. 1 cylinder is at TDC of ignition stroke (both rocker arms for No. 1 cylinder have clearance).
    NOTE: Crank pulley has 2 notches. When No. 1 cylinder is at TDC, upper notch will align with "0" notch on timing marker and lower crank pulley notch will be 750° counterclockwise from upper notch. (Second notch is TDC for No. 6 cylinder when aligned with "0" on timing marker).
  2. Adjust valves in sequence as follows:
    Intake Exhaust
    Cyl. 1 Cyl. 1
    Cyl. 2 Cyl. 3
    Cyl. 4 Cyl. 6
  3. Rotate crankshaft 360°. This will set No. 1 cylinder at TDC of exhaust stroke (rocker arms for No. 1 cylinder indicating no clearance). Adjust valves in following sequence:
    Intake Exhaust
    Cyl. 3 Cyl. 2
    Cyl. 5 Cyl. 4
    Cyl. 6 Cyl. 5
