Walk-Around Inspection
2. Remove the pipe from the high-pressure
turbocharger exhaust outlet and remove the air
intake pipe to the turbocharger. Visually inspect
the piping for the presence of oil. Clean the interior
of the pipes in order to prevent dirt from entering
during reassembly.
3. Remove elbow (2) and check for the presence of
engine oil.
4. Check for obvious heat discoloration of the
turbocharger. Check for any loose bolts or any
missing bolts. Check for damage to the oil supply
line and the oil drain line. Check for cracks in the
housing of the turbocharger. Ensure that the
compressor wheel can rotate freely.
5. Check for the presence of oil. If oil is leaking from
the back side of the compressor wheel, there is a
possibility of a failed turbocharger oil seal.
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.
6. Inspect the bore of the housing of the turbine outlet
for corrosion.
7. Install 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. For more information, refer
to Systems Operation, Testing, and Adjusting,
"Turbocharger - Inspect".

Typical example
Inspect the breather outlet pipe (1) for damage.
Ensure that the outlet tip (2) is clean and free from
any obstructions. Ice can cause obstructions in
adverse weather conditions.
Inspect the Engine for Leaks and
Loose Connections
A walk-around inspection should only take a few
minutes. When 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:
