WARNING: This page does not describe the selected car, but rather 16 other vehicles, including the 1996 Ford RV Cutaway, 1996 Ford Pickup, 1996 Ford F-Super Duty, 1996 Ford Econoline, and 1996 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
Check for loose connections or damage to air intake hoses and tubes.
Air leaks at the compressor manifold, intake manifold hoses or intake manifold covers can cause excessive smoke, loss of engine power or a noise condition.
Exhaust leaks at the exhaust manifolds or in the turbine housing will also cause loss of engine power and a noise condition.
Inspect turbocharger and components for loose connections or damage. Using a liquid soap on hose or tube connections will aid in leak detection.
Exhaust leaks can usually be detected audibly or visually by a discoloration caused by escaping hot exhaust gases.
