Exhaust Manifold, Dry (011-007)
General Information
Inspect for exhaust leaks at the exhaust manifold turbo-
charger, gasket leaks, or exhaust pipe, muffler or catalyst
restrictions. Leaks or restrictions will cause turbine and
impeller to operate at a lower speed and reduce the amount
of air being forced into the cylinder. Again, the symptom will
be excessive smoke, low manifold pressure, and low power.
