The overall performance and health of your vehicle depends on the condition of its exhaust system. Consisting of several parts, the exhaust system functions at its best when all components work harmoniously together. However, if one of its components aren’t at part with the rest, your entire exhaust system fails. Like other parts of a vehicle, the exhaust system also encounters issues along the way.
In this guide, we will enumerate the most common issues of exhaust systems.
Faulty Oxygen Sensor
Even though modern vehicles feature oxygen sensors, a malfunction with at least one can result in confusion to the rest of the vehicle. When one or more of the sensors give out, the computer system automatically troubleshoots the problem to create balance in the air-fuel mixture to ensure smooth operation. Although speedy in response, disproportionate combinations such as low air and high gas can result in clogs along the catalytic converter, which then leads to more serious damage.
Exhaust Leaks
Rough terrain is challenging to any type of vehicle regardless of model and make. If you regularly drive through rough roads, there is a high chance that your exhaust system wouldn’t last as long compared to vehicles that are typically driven along normal roads. Road imperfections such as holes and bumps can lead to weak areas, making parts such as joints to eventually split and leak poisonous fumes into the passenger cabin. This issue can be deadly especially when neglected or ignored by vehicle owners altogether.
If you notice any sign of leak or crack in your exhaust system, seek the expertise of a professional auto mechanic in Sydney right away.
Exhaust Smoke
A smoking car is inarguably dangerous, but there are still a few motorists who can’t differentiate between the colours of smoke that is emitted by their cars. A general rule to follow is that regardless of colour, it is imperative to take your car to a trusted car mechanic in Sydney if you see any signs of smoke emanating from your vehicle.
Here are the most common types of smoke and the problems associated with them:
- Blue Smoke indicated burning oil in the combustion chamber. Potential causes are worn out cylinder walls or PVC system, defective valve seals, non-functioning valve guides or piston rings.
- Black Smoke indicates excessive burning of fuel or wasting gas. This will cost you a lot of money when not taken care of by professionals. Black smoke may also mean a blocked fuel injector or clogged air filter.
- White or Gray Smoke may be due to burning coolant in the combustion chamber. This means that your cylinder head, head gasket, or coolant is suffering from a serious crack or damage.
Regardless of colour, smoke is never a good sign. Schedule a thorough examination and diagnostics with your trusted mechanic to determine the cause of smoke and to prevent further damage to your car and avoid unwanted accidents altogether.
Rust
Rust is the number one enemy of the exhaust system. The exhaust system is more susceptible to rust during shorter trips than long-distance travels. Short-distance travels are more stressful on the exhaust system due to the water vapor accumulation. Over time, condensation will turn to rust and cause severe corrosion on both the exterior and interior exhaust system. Salt from colder regions of the country predisposes to the development of rust when left ignored. Again, it’s best to conduct regular car servicing to ensure that your exhaust system is free from rust and corrosion.
Broken Hangers
The main function of hangers is to protect the exhaust system from banging around whenever you drive along rough terrain. It ensures the exhaust system is secured in its original position. When the hanger breaks or falls off, the exhaust pipes have more freedom of movement. Constant movement may lead to cracks, dents, and may break off in some cases. It is imperative to have them inspected routinely to ensure that the hangers are securing the exhaust system at all times.
Vibrations
Unusual vibrations from the steering wheel or gas pedal are signs that your exhaust system is encountering problems. In some cases, a malfunctioning exhaust system may cause your car to share severely, which may lead to accidents on the road. At the first sign of vibration, go to a trusted mechanic to have it checked and repaired.
Unusual Engine Noise
An increase in engine noise is the first sign of an engine leak. The leaks are usually found in the manifold or in joints along the exhaust system. If the leak is in the manifold, you will notice an increase in engine volume with added toxic fumes entering the passenger cabin. Inarguably, this is a serious issue that needs to be mediated as soon as possible.
