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.

WARNINGS:
Do not smoke or carry lighted tobacco or
open flame of any type when working on or near any fuel related components.
Highly flammable vapors are always
present and can ignite. Failure to follow
these instructions may result in personal
injury.
Do not carry out any repairs to the fuel
injection system without checking that the
fuel pressure has dropped to zero and that
the fuel temperature has either reached
ambient temperature or is below 30°C,
whichever is the greater. Failure to follow
these instructions may result in personal
injury.
1. Using datalogger in the Ford diagnostic
equipment , check that the fuel pressure has
dropped to zero and that the fuel temperature
has either reached ambient temperature or is
below 30°C, whichever is the greater.
