Check

  1. Refer to: Valve Cover (303-01A Engine - 1.0L EcoBoost (74kW/100PS)/1.0L EcoBoost (90kW/120PS)/1.0L EcoBoost (103kW/140PS) (YY), Removal and Installation).
  1. cautionNOTICE: Only rotate the crankshaft clockwise.

    Rotate the crankshaft until the corresponding piston is at TDC and then measure the valve clearance(s).
    Use the General Equipment: Feeler Gauge
  1. Note down each cylinder number and the valve clearances measured.
  1. Compare the measured valve clearance(s) with the specifications.
    Refer to: Specifications (303-01A Engine - 1.0L EcoBoost (74kW/100PS)/1.0L EcoBoost (90kW/120PS)/1.0L EcoBoost (103kW/140PS) (YY), Specifications).

Adjustment

  1. NOTE: The following steps are only necessary if adjustment is required.

  1. Refer to: Variable Valve Timing (VVT) Unit (303-01A Engine - 1.0L EcoBoost (74kW/100PS)/1.0L EcoBoost (90kW/120PS)/1.0L EcoBoost (103kW/140PS) (YY), Removal and Installation).
  1. Remove Special Service Tool: 303-1605.

  1.  
    • Remove the valve tappet and read the thickness from the underside.
    • The number on the valve tappet indicates the thickness of the bottom of the tappet. However, the number only indicates the digits after the decimal point (example: 725 = 2.725).
  1.  
    • Calculate the required thickness of the valve tappet with the following formula: X = S + M - V
    • Required thickness of tappet = X
    • Thickness of currently fitted tappet = S
    • Measurement of existing valve clearance (actual value) = M
    • Desired valve clearance = V
  1. Install the correct valve tappet.
  1. NOTE: Make sure that the components are installed to the position noted before removal.

  1. Install the camshafts approximately at valve overlap position cylinder No. 1.
  1. NOTE: Install all the bolts finger tight before final tightening.

    Tighten each bolt 2 turns at a time.
  1. Torque: 10 Nm

    1. Turn the camshafts to measure the valve clearance.
    1. Measure the valve clearances and repeat this procedure as necessary until all valve clearances are within the specified tolerance.
  1. NOTE: Note the position of the components before removal.
