Exhaust system, checking for leaks
- Start engine and run at idling speed.
- Plug tailpipe (e. g. with rag or stopper) and leave
plugged until check is complete.
- Listen for noise at connection points (cylinder
head/manifold, manifold/turbocharger,
turbocharger/catalytic converter, etc.) to locate
leaks.
- Correct any leaks that are found.
