The presence of oil may be the result of extended
engine operation at low idle. The presence of oil
may also be the result of a restriction of the line for
the intake air (clogged air filters), which causes the
turbocharger to slobber.
7. If engine oil is found in the system, the cause can
be the engine operating condition.
a. Ensure that the air duct (2) is clean and free
from dirt. Install air duct (2). Install bolt (3).
Ensure that the air intake is not clogged.
b. Operate the engine for 15 minutes at a
moderate high load condition.
c. Allow the engine to cool. Remove air duct and
check for the presence of engine oil. If the
deposits of wet engine oil have been removed,
the air duct can be installed and the engine can
operate normally. For more information, refer to
Systems Operation, Testing and Adjusting,
"Turbocharger - Inspect".
8. Inspect the bore of the housing of the turbine outlet
for corrosion.
9. Fasten the air intake pipe and the exhaust outlet
pipe to the turbocharger housing. Ensure that all
clamps are installed correctly and that all clamps
are tightened securely.
Walk-Around Inspection
Inspect the Tube of the Crankcase
Breather
Illustration 89
Typical example
Inspect the breather tube (1) for damage. Ensure that
the outlet (2) is clean and free from any obstructions.
Ice can cause obstructions in adverse weather
conditions.
Inspect the Engine for Leaks and
for Loose Connections
A walk-around inspection should only take a few
minutes. When the time is taken to perform these
checks, costly repairs and accidents can be avoided.
For maximum engine service life, make a thorough
inspection of the engine compartment before starting
the engine. Look for items such as oil leaks or
coolant leaks, loose bolts, worn belts, loose
connections, and trash buildup. Make repairs, as
needed:
• The guards must be in the correct place. Repair
damaged guards or replace missing guards.
