• Faulty positive crankcase vent-
ilation (PCV) system.
- Hoses or ventilation orbreather valves are blocked.
This causes excessive
pressure in the crankcase
which causes more oil to
enter the combustion
chamber.
- PCV oil separator is faulty and engine oil can enter the
combustion chamber
through the intake manifold.
• INSTALL a new turbocharger.Engine - 2.5L Duratec-ST (VI5)
-

• Damaged gaskets or mating
surfaces.
- Cylinder head gasket isdamaged or mating face are
warped.
- Valve stem seals are worn and engine oil can enter the
combustion chamber
between the valve stem and
the valve stem guide.
• INSTALL new components asnecessary.
• Piston ring or cylinder liner
wear.
• CHECK the running surfacesand clearances of the individual
engine components. INSTALL
new components as necessary.
INSTALL a new cylinder block
if necessary.
• Check the pistons and piston rings.
