2.
The crankcase breather is restricted.
The crankcase breather (if equipped), or the tubing must
be cleaned or replaced.
3.
A restriction exists in the tube between the air filter and
the turbocharger.
The component must be cleaned and replaced.
4.
An air leak or restriction exists in the line between the
turbocharger and the intake manifold.

5.
The turbocharger is loose or the clamps and bolts on
the turbocharger are loose.
Correctly position the turbocharger and tighten the
clamps and bolts.
6.
Air or combustion gas is leaking through the seals of the
