Tips For Noticing Issues With Exhaust Manifolds
Drive safely by learning how to spot the symptoms of exhaust manifold problems.
There are so many parts to your vehicle that it seems too daunting of a task to try to know what goes on inside of it. But fortunately, cars tend to show symptoms before breaking. Especially when it comes to the exhaust manifold, the symptoms of problems may be easier to spot than you think.
The exhaust manifold is an important part of the exhaust system that expels gases from the engine into the exhaust pipes and out of the vehicle. It ensures that gases do not enter other areas of the combustion system. When the exhaust manifold leaks, it may cause problems with your car, the environment and your health. So here are some symptoms to look out for.
First of all, if you smell gases, the exhausted manifold may be broken. As mentioned above, its main function is to route gases where they should go. Hence a strong odor of gas is a major symptom of a leak. Leaked gases could also be related to bigger issues with your vehicle. In this case, immediate maintenance check is recommended.
Second, listen for unusual engine sounds. This includes anything that is too loud or strange knocking sounds. If it is difficult to distinguish weird sounds while driving, try taking sometime to listen carefully when you are at a full stop. For example, when you are starting the car and you hear a loud noise near the engine, you could have a leak in the exhaust manifold.
Third, visually examine the area where the exhaust manifold and cylinder head meet. Putting the car on a lift may be required for this method. If some pieces of the exhaust gasket are protruding far more than the rest, those places could be the points of failure. Also look for a stained cylinder head or exhaust manifold. These are signs of a sooty exhaust, which could be due to a leak in the exhaust manifold.
Fourth and the most straight-forward way to detect an exhaust manifold problem is to see if you can pass the emissions test. If your vehicle fails the test, it could be due to a leak in the exhaust manifold. When there is a leak, oxygen enters the exhaust stream, so that higher emissions occur from your car.
Failing an emissions test could also be due to other issues in the emissions system of your car. A trained mechanic can help you determine what exactly caused the emissions test failure and how to prevent it in the future.
