Exhaust System: Testing and Inspection

Exhaust System, Checking For Leaks
^ Start engine and run at idling speed.
^ Plug the tailpipe (e. g. with rags or stoppers) and leave plugged until the check is complete.
^ Listen for noise at the connection points (cylinder head/exhaust manifold, exhaust manifold/turbocharger, turbocharger/front exhaust pipe etc.) to determine whether there are any leaks.
^ Repair any leaks that are found.
