Exhaust System: Testing and Inspection

Checking exhaust system for leaks

^ Start engine and run at idling speed.
^ Plug tailpipes with cloths or stoppers, etc. until leakage check is completed.
^ Listen for noise at the connection points (cylinder head/manifold, manifold/turbocharger, turbocharger/catalytic converter, etc.) to locate any leaks.
^ Rectify any leaks that are found.
