A Series Diesel Engine Air System 100
Damage From Non-Filtered Air
Loose connections or cracks in the suction side of the
intake pipe can allow debris to be ingested by the
engine causing rapid wear in the cylinders.
Leaks at the intake manifold, unsealed bolt holes or
manifold cover gasket can also all dust and dir to be
ingested into naturally aspirated engines.
Loose connections or cracks in the suction side of the
intake pipe on turbocharged engines can allow debris
to be ingested into the turbocharger compressor and
forced into the engine.
Debris drawn into the air suction side can damage the
compressor blades causing and imbalance resulting in
a bearing failure.
To verify a bearing failure or damaged compressor,
remove the intake and exhaust piping and check for
contact. The rotor assembly must rotate freely.
Measurement of axial and radial clearance is
described in this Section.
Pressure Side Air Leaks
(Turbocharged Engines)
Excess smoke and low power from a turbocharged
engine can be caused by pressurized air leaking from
loose connections or cracks in the crossover tube or
intake manifold.
