4. DIAGNOSTIC INFORMATION AND PROCEDURE
1) 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 ▶
Identify the fluid. Determine whether it is engine oil, automatic transmission fluid, power steering
fluid, etc.
Identify where the fluid is leaking from. -
-
After running the vehicle at normal operating temperature, park the vehicle over a large sheet
of paper.
Wait a few minutes.
You should be able to find the approximate location of the leak by the drippings on the paper. ·
·
·
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.
If the leak still cannot be found, it may be necessary to clean the suspected area with a
degreaser, steam or spray solvent. -
-
Clean the area well.
Dry the area.
Operate the vehicle for several miles at normal operating temperature and varying speeds.
After operating the vehicle, visually check the suspected component.
If you still cannot locate the leak, try using the powder or black light and dye method. ·
·
·
·
·
Clean the suspected area.
Apply an aerosol-type powder (such as foot powder) to the suspected area.
Operate the vehicle under normal operating conditoins.
Visually inspect the suspected component. You should be able to trace the leak path over the
white powder surface to the source. -
-
-
- Powder Method ▶

01-10
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.
Pour the specified amount of dye into the engine oil fill tube.
Operate the vehicle normal operating conditions as directed in the kit.
Direct the light toward the suspected area. The dyed fluid will appear as a yellow path leading to
the source. -
-
-
Once the origin of the leak has been pinpointed and traced back to its source, the cause of the leak must
be determined in 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.Repairing the Leak ▶
Gaskets ▶
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. -

2) Compression Pressure Test
Standard Service Data ▶
A9912 0012B (001 589 76 21 00) Compression Pressure Tester -
Measuring Procedure ▶
Warm the engine up to normal operating temperature.
Remove the spark plugs using the spark plug wrench.
Place the diagram sheet to compression pressure tester A9912 0012B (001 589 76 21 00).
Connect the adaptor to compression pressure tester A9912 0012B (001 589 76 21 00) and
install it into the spark plug hole.
Crank the engine approx. eight revolutions by using the start motor.
Compare the measurements of compression pressure tester A9912 0012B (001 589 76 21 00)
with the specifications.
Measure the compression pressure of the other cylinders in the same way.
If measured value is not within the specifications, perform the cylinder pressure leakage test. -
-
-
-
-
-
-
-
Discharge the combustion residues in the cylinders before testing the compression pressure.
Apply the parking brake before cranking the engine. -

Leakage Test ▶
Warm the engine up to normal operating temperature.
Disconnect the negative battery cable.
Remove the spark plugs.
Check the coolant level by opening the coolant reservoir cap and replenish if insufficient.
Open the engine oil filler cap.
Connect the tester to air pressure line and adjust the scale of tester.
Install the connecting hose to spark plug hole.
Position the piston of No.1 cylinder at TDC by rotating the crankshaft.
Connect the connecting hose to tester and measure the leakage volume after blowing up
5 bar of compressed air. -
-
-
-
-
-
-
-
-
Measure the leakage volume in the completely opening condition of throttle valve by pulling the
acceleration cable. -
Perform the pressure test according to the firing order. -
Firing Order: 1 - 3 - 4 - 2 -
Compare the leakage pressure with the specifications. -
