OIL LEAK DIAGNOSIS
Most fluid oil leaks are easily located and repaired by
visually finding the leak and replacing or repairing the
necessary parts. On some occasions a fluid leak may
be difficult to locate or repair. The following procedures
may help you in locating and repairing most leaks.
Finding the Leak
1. Identify the fluid. Determine whether it is engine oil,
automatic transmission fluid, power steering fluid, etc.
2. Identify where the fluid is leaking from.
2.1 After running the vehicle at normal operating
temperature, park the vehicle over a large sheet
of paper.
2.2 Wait a few minutes.
2.3 You should be able to find the approximate
location of the leak by the drippings on the
paper.
3. Visually check around the suspected component.
Check around all the gasket mating surfaces for
leaks. A mirror is useful for finding leaks in areas that
are hard to reach.
4. If the leak still cannot be found, it may be necessary
to clean the suspected area with a degreaser, steam
or spray solvent.
4.1 Clean the area well.
4.2 Dry the area.
4.3 Operate the vehicle for several miles at normal
operating temperature and varying speeds.
4.4 After operating the vehicle, visually check the
suspected component.
4.5 If you still cannot locate the leak, try using the
powder or black light and dye method.
Powder Method
1. Clean the suspected area.
2. Apply an aerosol-type powder (such as foot powder)
to the suspected area.
3. Operate the vehicle under normal operating
conditoins.
4. Visually inspect the suspected component. You
should be able to trace the leak path over the white
powder surface to the source.
Black Light and Dye Method
A dye and light kit is available for finding leaks, Refer to
the manufacturer's directions when using the kit.
1. Pour the specified amount of dye into the engine oil
fill tube.
2. Operate the vehicle normal operating conditions as
directed in the kit.
3. Direct the light toward the suspected area. The dyed
fluid will appear as a yellow path leading to the
source.
Repairing the Leak
Once the origin of the leak has been pinpointed and
traced back to its source, the cause of the leak must be
determined n order for it to be repaired properly. If a
gasket is replaced, but the sealing flange is bent, the
new gasket will not repair the leak. The bent flange must
be repaired also. Before attempting to repair a leak,
check for the following conditions and correct them as
they may cause a leak.
Gaskets
lThe fluid level/pressure is too high.
lThe crankcase ventilation system is malfunctioning.
lThe fasteners are tightened improperly or the threads
are dirty or damaged.
lThe flanges or the sealing surface is warped.
lThere are scratches, burrs or other damage to the
sealing surface.
lThe gasket is damaged or worn.
lThere is cracking or porosity of the component.
lAn improper seal was used (where applicable).
Seals
lThe fluid level/pressure is too high.
lThe crankcase ventilation system is malfunctioning.
lThe seal bore is damaged (scratched, burred or
nicked).
lThe seal is damaged or worn.
lImproper installation is evident.
lThere are cracks in the components.
lThe shaft surface is scratched, nicked or damaged.
lA loose or worn bearing is causing excess seal wear.

Measuring Procedure
1. Warm the engine up to normal operating temperature.
2. Remove the spark plugs.
3. Place the diagram sheet to compression pressure
tester.
4. Connect the adaptor to compression pressure tester
and install it into the spark plug hole.
5. Crank the engine approx. eight revolutions by using
the start motor.
6. Compare the measurements of compression
pressure tester with the specifications.
7. Measure the compression pressure of the other
cylinders in the same way.
8. If measured value is not within the specifications,
perform the cylinder pressure leakage test.
Notice
lDischarge the combustion residues in the cylinders
before testing the compression pressure.
lApply the parking brake before cranking the
engine.
