DIAGNOSIS

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 loca-

tion 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 condi-

tions.

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 gas-

ket 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

The fluid level/pressure is too high.

The crankcase ventilation system is malfunctioning.

The fasteners are tightened improperly or the threads

are dirty or damaged.

The flanges or the sealing surface is warped.

There are scratches, burrs or other damage to the

sealing surface.

The gasket is damaged or worn.

There is cracking or porosity of the component.

An improper seal was used (where applicable).

Seals

The fluid level/pressure is too high.

The crankcase ventilation system is malfunctioning.

The seal bore is damaged (scratched, burred or

nicked).

The seal is damaged or worn.

Improper installation is evident.

There are cracks in the components.

The shaft surface is scratched, nicked or damaged.

A loose or worn bearing is causing excess seal wear.
