  1. Remove the valve cover.
    For additional information, refer to Valve Cover - in this section.

  1. Using the special tool, remove the spark plugs.
  1. CAUTION:
    CAUTION:Only rotate the crankshaft in the normal direction of rotation.
    Rotate the crankshaft until piston No. 1 is at top dead center (TDC).

  1. NOTE:
    NOTE:Make a note of each cylinder number and the valve clearances measured.
    Using a suitable set of feeler gauges, measure the valve clearances.
  1. CAUTION:
    CAUTION:Only rotate the crankshaft in the normal direction of rotation.
    Rotate the crankshaft until each piston is at TDC and measure the valve clearances.
  1. NOTE:
    NOTE:Only carry out the following steps when the valve clearance(s) require adjustment.
    For additional information, refer to Specification - in this section.
    Remove the camshafts.
    For additional information, refer to Camshafts - in this section.
  1. NOTE:
    NOTE:The number on the valve tappet is the valve tappet thickness, however only the decimal places are marked (for example .650 = 3.650).
    Determine the valve tappet thickness required:
    1. Remove the valve tappet and read the thickness from the underside.
    1. Valve tappet thickness required = thickness of currently installed valve tappet + the measured valve clearance - the required valve clearance.
      For additional information, refer to Specification - in this section.
    1. Install the correct valve tappet.
  1. NOTE:
    NOTE:Do not install the valve cover at this stage.
    Install the camshafts.
    For additional information, refer to Camshafts - in this section.
  1. CAUTION:
    CAUTION:Only rotate the crankshaft in the normal direction of rotation.
    Rotate the crankshaft until each piston is at TDC and measure the valve clearances.
  1. Repeat this procedure as necessary until all valve clearances are within the specified tolerance.

  1. Using the special tools, install the spark plugs.
  1. Install the valve cover.
    For additional information, refer to Valve Cover - in this section.
