Turbocharger Leak Test
- 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.
