OIL LEAK DIAGNOSIS Most fluid oil leaks are easily located and repaired by visually finding the leak and replacing or repairing thenecessary parts. On some occasions a fluid leak may
be difficult to locate or repair. The following proceduresmay 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 forleaks. A mirror is useful for finding leaks in areas thatare hard to reach.
4. If the leak still cannot be found, it may be necessary to clean the suspected area with a degreaser, steamor 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 agasket 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 asthey 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 thesealing 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.

Leakage Test1. Warm the engine up to normal operating temperature.
2. Disconnect the negative battery cable.
3. Remove the spark plugs.
4. Check the coolant level by opening the coolant surge tank cap and replenish if insufficient.
5. Open the engine oil filler cap.
6. Connect the tester to air pressure line and adjust the scale of tester.
7. Install the connecting hose to spark plug hole.
9. Connect the connecting hose to tester and measure the leakage volume after blowing up 5bar of compressed air. Notice Measure the leakage volume in the completely opening condition of throttle valve by pulling the acceleration cable.
10. Perform the pressure test according to the firing order.
Notice Firing Order : 1 - 5 - 3 - 6 - 2 - 4
11. Compare the leakage pressure with the specifications. 8. Position the piston of No.1 cylinder at TDC by rotating the
crankshaft.

GENERAL INFORMATION
CLEANLINESS AND CARE An automobile engine is a combination of many machined, honed, polished and lapped surfaces withtolerances that are measured in the ten-thousanths ofan inch. When any internal engine parts are serviced,care and cleanliness are important. A liberal coating of enigne oil should be applied to friction areas during
assembly, to protect and lubricate the surfaces on initialoperation. Proper cleaning and protection of machinedsurfaces and friction areas is part of the repairprocedure. This is considered standard shop practice even if not specifically stated. Whenever valve train components are removed for
service, they should be kept in order. They should beinstalled in the same locations, and with the same matingsurfaces, as when they were removed. Battery cables should be disconnected before any majorwork is performed on the engine. Failure to disconnectcables may result in damage to wire harness or other electrical parts. ON-ENGINE SERVICE Caution: Disconnect the negative battery cable before removing or installing any electrical unit, or when a tool or equipment could easily come in contact with exposed electrical terminals.Disconnecting this cable will help prevent personalinjury and damage to the vehicle. The ignition mustalso be in LOCK unless otherwise noted. Notice:
Any time the air cleaner is removed, the intake
opening should be covered. This will protect against accidental entrance of foreign material, which could follow the intake passage into the cylinder and cause extensive damage when the engine is started.
