system
2. Visually inspect for obvious signs of mechanical or electrical damage.
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible)
before proceeding to the next step.
4. If the cause is not visually evident, verify the symptom and refer to the Symptom Chart.

Symptom
• CHECK for evidence of oilleaks on components. Use an
ultraviolet (UV) leak tester if an
oil leak is not evident. INSTALL
new gaskets or components as
required.
• Oil leaks on components that
are either coated in oil them-
selves or on components local
to them.
• Loss of oil
• CHECK the coolant expansiontank for a film of oil on the
coolant surface. INSTALL a
new oil cooler or oil cooler
gasket.
• Internal or external leak at the
oil cooler.
• INSTALL a new crankshaftseal.
• Leak at the crankshaft seal.
• CHECK for cracks in oil-carrying components of the
basic engine by means of a UV
leak test. INSTALL new
components or seals as
necessary.
• Leaks from oil carrying
components or basic engine.
• DETERMINE the last type ofengine oil used and compare
with the specification. Change
the engine oil to the specifica-
tion.
• Use of the wrong type of engine
oil.
• Oil consumption

Symptom
• CHECK if the PCV system isoperating correctly and repair
as necessary. Engine - 2.5L
Duratec-ST (VI5) -
REFER to: Engine Emission
Control (303-08 Engine

Engine - 2.0L Duratorq-TDCi
(DW) Diesel -
• 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)
-
REFER to: Turbocharger (303-
04 Fuel Charging and
Controls - Turbocharger -

tion).
Engine - 2.0L Duratorq-TDCi
(DW) Diesel -
• Turbocharger seals.
• CHECK the gaskets and matingsurfaces for damage.
Remove the cylinder head.
CHECK the mating faces, cylinder
head gasket and the evenness of
the cylinder head and engine block
mating faces.
INSTALL new valve seals. Engine
- 2.5L Duratec-ST (VI5) -

Engine - 2.0L Duratorq-TDCi (DW)
Diesel -
• 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.
• Damaged cylinder liners or
excessive clearance of engine
components.
- Pistons.
- Piston rings (clearance ingroove and end gap).
- Cylinder liners.
