Exhausts can fail for a number of reasons. There are a number of tell-tale signs of potential exhaust problems. If you notice any of the following you should have your exhaust checked.
Noises such as a rattling noise may indicate loose brackets holding the system in place. Alternatively, a roaring noise could be a potential problem with the silencer. Finally, hissing or popping could be a sign that one of the pipes is leaking.
You may also notice a change in emissions such as blue or white smoke. Blue smoke indicates a possible fault in the engine, putting burnt oil into the exhaust system. On the other hand, white smoke could be due to an internal coolant leak. In either case your vehicle will need to be examined.
Smells, such as exhaust fumes in or around the vehicle may be the first sign of exhaust system leaks. Ensure you have this checked out promptly at Alastair Reid Garages to prevent further problems.
Also, don't ignore the importance of visual appearance as the presence of rust or corrosion on the pipe as well as cracks, especially where the pipes connect could indicate a problem.
