1. DESCRIPTION AND OPERATION
1) Cleanliness and Care
An automobile engine is a combination of many machined, honed, polished and lapped surfaces
with tolerances that are measured in the ten-thousanths of an 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 initial operation. Proper cleaning and protection of machined surfaces
and friction areas is part of the repair procedure.
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 be installed in the same locations, and with the same mating surfaces, as when they were
removed.
Battery cables should be disconnected before any major work is performed on the engine. Failure
to disconnect cables may result in damage to wire harness or other electrical parts.

2) On-engine Service
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 personal injury and damage to the vehicle. The
ignition must also be in LOCK unless otherwise noted. -
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. -

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. -
