How long will it take to fix an exhaust leak? Exhaust leak repairs usually take between two and three hours to complete. In some cars, it may take less time, while in others it will take longer. It just depends on how difficult it is to get to the exhaust manifold and repair costs around $125 to $300 to pay for labor costs.
All motorized vehicles have exhaust as exhaust gas channels from the rest of the combustion. As your vehicle ages, the exhaust can age and its performance will degrade over time, so there is always a chance that your car's exhaust will leak.
Before a car owner needs to know what are the signs or characteristics of a leaky exhaust, you need to know the exhaust components first. The first part, exhaust manifold, exhaust pipe, and catalytic converter which functions as a filter for harmful substances.
The second part, the resonator and muffler to muffle the exhaust sound. Then, the last exhaust as the last exhaust. In addition, there is also an exhaust gasket to maintain tightness between the cylinder block and the exhaust neck to prevent exhaust leakage.
Well, you know, exhaust is always in direct contact with hazardous waste substances that are corrosive. This can result in a leak in the exhaust. Therefore, you need to always pay attention to the condition of your exhaust.
Causes and signs of a leaky car exhaust
The cause of a leaking exhaust is usually a hole or crack. Holes or cracks in the exhaust can be caused by the age of the vehicle that is long enough so that the exhaust wears out or human error occurs.
Human error in question, for example, vehicle maintenance that is not optimal or is exposed to friction or hard impact on the bottom, especially on a flat car.
Exhaust leaks can also be caused by a leaking exhaust gasket. As previously explained, the exhaust gasket functions to maintain the density between the exhaust neck and the cylinder block to prevent leakage. However, if the gasket is leaking, the exhaust is likely leaking too.
After knowing the cause, don't forget to recognize the characteristics of a leaky exhaust below.
1. Exhaust sound is not round
Listening to the exhaust sound is an easy way to detect a leaky exhaust. Signs of a leaking exhaust are usually marked by a loud noise or hissing in the middle when the engine is started and gassed.
2. Engine performance decreases
In addition to sound, leaking exhaust can also be detected from the declining performance of the car's engine.
For example, when you step on the gas pedal but the car doesn't go fast, it could be a leaking exhaust, especially if it's accompanied by a hissing or loud exhaust sound. In addition, cars are also wasteful of gasoline.
The impact if the car exhaust is left leaking
Judging from the characteristics of a leaking exhaust, it will certainly cause an uncomfortable effect. Especially if the sound of the exhaust sounds loud when the vehicle is turned on. However, not only that, a leaking exhaust can have an impact on the car engine.
A leaky exhaust can also trigger fatal car damage. Moreover, it can encourage overheating conditions in the engine. If this continues, the car could be damaged.
As a result of a leaky exhaust also has an impact on the health of other motorists. Dangerous exhaust gases that must be filtered several times on the exhaust components, so that they do not function properly when the exhaust leaks.
So that if these harmful substances are inhaled by other drivers, it can increase the risk of heart and lung, and even cancer risk.
It is also possible that if the exhaust gas leaks, inhaled by the car owner itself, it will also have a bad impact on health.
If you think your car's exhaust smells too strong and there are signs of an exhaust leak, have it checked immediately. Including if you use an exhaust gasket, it could be that the component has a leak.

How to fix a leaky car exhaust
Don't even think about replacing your vehicle when you experience an exhaust leak. You can still fix a leaky exhaust in the following way.
1. Using heat-resistant glue
The way that can be done to overcome a leaky exhaust is to use heat-resistant glue. Glue that can be used includes iron glue, sealer glue, or other glue that is formulated to be heat resistant.
Iron glue can be found at the nearest building shop. If you choose a glue sealer, make sure the sealer glue you buy is heat resistant.
How to patch a leaky car exhaust with glue is relatively easy. You need to first detect the location of the leak, then apply glue to the leaking exhaust.
2. Using aluminum tape
Usually aluminum seal tape is used to patch a leaky pan. However, this seal tape can be used to repair a leaky exhaust. Glue it on holes or cracks to patch leaks in the car exhaust.
3. Replace exhaust gasket
Maybe patching the exhaust isn't effective enough. There you fix a leaky car exhaust by replacing the gasket. However, replacing the exhaust gasket should not be done alone. Leave the technician at the repair shop to fix it.
4. Go to the workshop to weld
Another way that can be done is to weld carbide to patch a leak in the car exhaust.
Carbide welding cannot be done at home. So, you need to come to a car repair shop to ask a technician for help to fix exhaust leaks with carbide welding.
