Exhaust Troubleshooting

Here are some of the common problems that you may encounter with the exhaust on your vehicle, we will go over the causes, symptoms and how we repair the fault.

Silencer
The silencer is the part of the exhaust that usually needs attention first, as it is the furthest away from the engine and is the most likely to be corroded by acidic moisture. The reasons for this because these parts remain cooler and give exhaust fumes the chance to condense and generate pools of corrosive acid inside the system causing damage.

This is an easy fault to spot due to the ability to see the fault with a visual inspection, things to look out for include discolouring and rust.

When this occurs the affected part needs to be replaced and depending on the extent of the damage, the whole exhaust may need to be replaced.

Cracked exhaust manifold
The exhaust manifold is the exhaust unit as a whole and includes all the piping from the engine through to the exhaust port. A common damage that occurs is the manifold becomes damaged due to knocks and bumps while driving. Corrosion can also be a factor in the exhaust manifold developing cracks.

The most common symptom for this fault is the noise that the exhaust makes, most notably is a hissing sound indicating a crack in the manifold.

This fault can be repaired by either replacing the different joints that may be cracked or damaged. In some cases due to the parts becoming fused together by corrosion and heat, the entire exhaust manifold may have to be replaced.

Loose exhaust
If you hear rattling under the car it could mean that the exhaust system has become misaligned, if you can hear a loud metallic vibration, it usually means that something is touching the exhaust pipe or that a clamp, support bracket or mounting is loose. Hangers and brackets hold your exhaust in place. Corroded, fractured or missing hangers or brackets can cause extra stress which can also lead to premature exhaust failure.

There are many ways this fault can be rectified, we can repair any damaged brackets, replace supports that may have come loose over time and replace the entire exhaust manifold depending on the damage.

As seen above exhaust systems can fail for a number of reasons; accidental damage, faulty components, or simple wear and tear. Any of these causes can lead to broken studs, blown gaskets, leaking and corroded joints, loose clamps, detached mountings, severed pipe work and fractured catalytic converters.
