  1. Remove the engine cover.
  1. Disconnect the battery ground cable.
    For additional information, refer to: Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures).

  1. Disconnect the camshaft position (CMP) sensor electrical connector.

  1. Disconnect the positive crankcase ventilation (PCV) hose from the valve cover.

  1. Remove the ignition coil-on-plug.

  1. Using the special tool, remove the spark plugs.

  1. Remove the engine cover retaining brackets.

  1. Remove the valve cover.
  1. NOTE:
    NOTE: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:Note down each cylinder number and the valve clearances measured.
    Using a suitable set of feeler gauges, measure the valve clearances.
  1. NOTE:
    NOTE: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: Specifications (303-01 Engine - 1.8L Duratec-HE (MI4)/2.0L Duratec-HE (MI4), Specifications).
    Remove the camshafts.

  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. Calculate the valve tappet thickness required (thickness of currently installed valve tappet, + the measured valve clearance, - the required valve clearance).
      For additional information, refer to: Specifications (303-01 Engine - 1.8L Duratec-HE (MI4)/2.0L Duratec-HE (MI4), Specifications).
    1. Install the correct valve tappet.
  1. NOTE:

  1. NOTE:
    NOTE: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. Apply a small bead of sealant to the areas as shown.

  1. NOTE:
    NOTE:Install a new valve cover gasket if necessary.
    Install the valve cover.
    • Tighten the bolts in the sequence shown.
