Exhaust system checks (Skoda Favorit)

25. The exhaust system is checked on a cold engine. To facilitate the check, lift the car and place it on axle stands so that all components of the exhaust system are visible and accessible.

26. Check the exhaust pipe and connections for signs of leaks, corrosion and damage. Make sure all brackets and fasteners are in good condition and that all nuts and bolts are tight. A leak at any of the connections or elsewhere in the system will usually show up as a black, sooty spot near the leak.

27. Rattling and other noises are often heard in the exhaust system, especially brackets and fasteners. Try to relocate the pipes and mufflers. If the components come into contact with the body or suspension parts, secure the system with new fasteners. Otherwise, separate the connections (if possible) and wrap the rods as needed with heat-resistant material to take up the play.

28. Run the engine at idle speed, then cover the exhaust pipe outlet with a cloth and check for exhaust leaks along the entire length of the system.

29. Finally, lower the car to the ground.

30. The condition of the engine can be determined by the condition of the inside of the exhaust pipe. If there is carbon deposits, the engine needs repair. If the pipe is black and sooty, the engine needs adjustment, including a complete inspection and adjustment of the fuel system.
