Refer to: Valve Cover (303-01B Engine - 1.6L EcoBoost (132kW/180PS) – Sigma, Removal and Installation).
-
NOTICE:
Only use hand tools when removing or installing the
spark plugs, or damage can occur to the cylinder head or spark plug.
NOTE:
Use compressed air to remove any foreign material in the spark plug well before removing the spark plugs.
-
-
NOTE:
Turn the engine clockwise only and use the crankshaft bolt only.
NOTE:
Measure the valve clearance at base circle, with the
lobe pointed away from the tappet, before removing the camshafts.
Failure to measure all clearances prior to removing the camshafts will
necessitate repeated removal and installation and wasted labor time.
Measure each valve's clearance and record its location.
Use the General Equipment: Feeler Gauge
-
NOTE:
The nominal clearance is:
-
intake: 0.0118 in (0.3 mm)
-
exhaust: 0.0157 in (0.4 mm)
NOTE:
The acceptable clearance is:
-
intake: 0.010–0.014 in (0.255–0.345 mm)
-
exhaust: 0.014–0.018 in (0.355–0.445 mm)
Replace the valve tappets as needed.
Adjustment
-
Refer to: Camshafts (303-01B Engine - 1.6L EcoBoost (132kW/180PS) – Sigma, Removal and Installation).
-
NOTE:
The number on the valve tappet only reflects the
digits that follow the decimal. For example, a tappet with the number
has the thickness of 3.650 mm.
NOTE:
Select the closest tappet size to the ideal tappet thickness available and mark the installation location.
Select tappets using this formula: tappet thickness =
measured clearance + the existing tappet thickness - nominal clearance.
-
Install the correct valve tappet.
-
NOTE:
Install a new O-ring seal.

NOTICE:
Failure to follow the camshaft tightening procedure can result in damage to the camshafts.
NOTE:
Make sure that the components are installed to the location and orientation noted before removal.
NOTE:
Make sure that the mating faces are clean and free of foreign material.
NOTE:
Make sure that new bolts are installed.
NOTE:
Apply clean engine oil to the bearing surfaces of the camshafts, camshaft bearing caps and the VCT bridge.
Tighten the bolts evenly, half turn at a time, until the crankshaft
bearing caps and the VCT bridge are seated against the cylinder head.

Check
NOTE:
No factory-equipped vehicle should have more than a 25 mA
(0.025 amp) – 50 mA (0.050) draw depending on the vehicle's accessories.
Check for current drains on the battery in excess of 25 mA (0.025 amp) –
50 mA (0.050) with all the electrical accessories off and the vehicle
at rest for at least 40 minutes. Current drains can be tested with the
following procedure.

Removal
NOTICE:
Suspension fasteners are critical parts that affect
performance of vital components and systems. Failure of these fasteners
may result in major service expense. Use the same or equivalent parts if
replacement is necessary. Do not use a replacement part of lesser
quality or substitute design. Tighten fasteners as specified.
Remove the brake drum.
