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

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.

Engine - Oil Leaks
NOTE:
Before installing new gaskets or oil seals,
make sure that the fault is clearly established.
If the oil leak cannot be identified clearly by a visual
inspection, carry out an ultraviolet (UV) test:
Ultraviolet (UV) Testing
1. Clean the engine and transmission with a suitable cleaning fluid.
2. Pour the UV-test fluid in accordance with the quantity specified by the manufacturer through
the oil filler neck into the engine and install the
oil filler cap.
WARNING: Vehicles with manual transaxle,
shift the transaxle into Neutral. Failure to
follow this instruction may result in
personal injury.
3. Start the engine and let it run for about five minutes.
4. Switch off the engine.
NOTE: If no leak can be found, road test the
vehicle under various loads and check the engine
for leaks again.
5. Check the engine for oil leaks using a suitable UV lamp.
6. Rectify any leaks found and check the engine for oil leaks.
Measure the compression pressure
NOTE: The powertrain control module (PCM)
receives an error message when the fuel pump
relay is removed or electrical components are disconnected. This error message must be deleted
from the fault memory using the Ford diagnostic
equipment after completing the compression test.
NOTE:
Valve clearance must be set correctly
before performing a compression test. Make sure
the engine is at the normal operating temperature.
NOTE: The varying design of compression
checking devices and fluctuating starter motor
speeds normally only allows for a comparison to
be made of the compression pressures in all
cylinders.
