A Series Diesel Engine Air System 102
Oil Consumption and Leaks
Engine lubricating oil is used to lubricate the bearings
and provide some cooling for the turbocharger.
The oil is supplied to the turbocharger through the
supply line is at engine operating pressure.
A return line connected to the bottom of the
turbocharger routes the oil back to the engine oil pan.
Seals are used on each end of the rotor assembly.
The primary function of the seals is to prevent exhaust
gases and compressed air from entering the
turbocharger housing. Oil leakage from the seals is
rare, but it can occur.
A restricted or damaged oil return line will cause the
turbocharger housing to be pressurized causing oil to
migrate by the seals.
Additionally, high intake or exhaust restrictions can
cause a vacuum between the compressor and the
turbocharger housing resulting in oil leaking by the
seals.
