How can I tell if there is a problem with my exhaust system?
Listen out for unusual sounds coming from your exhaust system. A noisy exhaust or an exhaust that is making strange sounds is a sure way to detect a problem as well as indicate potential damage. The silencer is the part of the exhaust that usually needs attention first due to its tendency to become corroded by acidic moisture.
Where does the noise from the exhaust come from?
If it occurs in the intake system, the noise will come from the fuel system (fuel injector throttle body) and if from the exhaust system (which is most common) will come from the exhaust pipe. What causes a backfire?
What kind of patch do I need for my exhaust pipe?
Using a Patch to Help Seal Leaks Determine the size of patch needed. You can purchase exhaust patch kits from your local auto parts store, but cutting up a piece of an aluminum can will actually do just as good as job at serving as a patch for a larger exhaust leak. Cut an aluminum patch to fit over the leak.
What does white smoke coming from the exhaust mean?
However, if the exhaust continues to emit white smoke for an extended period of time, this suggests your engine is burning coolant and you may have a problem with your cylinder head or have a cracked head gasket. If coolant is leaking into your engine oil it will appeared discoloured and creamy.

What are the common problems with car exhaust?
These silence certain frequencies coming from the exhaust. Another of the common car exhaust problems is exhaust restriction. You probably have exhaust restriction if your car is losing power or if you are using too much fuel.
What to do if you have an exhaust restriction problem?
To remedy this car exhaust problem, you need to solve the root of the problem such as unplugging the catalytic converter if the problem is a plugged catalytic converter. To determine if you have an exhaust restriction problem, read your engine’s manifold vacuum when the car is idle.
Do you need a mechanic to fix an exhaust problem?
You do not need a mechanic to fix common car exhaust problems. It is important to catch exhaust problems early because if the exhaust system goes unchecked, it can lead to engine problems since the exhaust system’s purpose is the removal of harmful elements from engines.
Why do I have a problem with my exhaust system?
Your car is experiencing a loss of power and acceleration. The exhaust system is designed to optimize the emissions performance and acceleration of the car. If there is a sudden decrease in your car’s acceleration power, this can indicate some type of exhaust system issue, like a clogged exhaust manifold.
What are the common problems with exhaust manifolds?
Common Problem: Exhaust manifolds are prone to damage from one of two things. The first is the exposure to cycles of extreme pressure and heat. The manifold then becomes so worn that it is unable to withstand the heat and cracks begin to form. Cracks can develop into small holes causing complete failure.
Is it possible to diagnose an exhaust problem?
While it’s possible to diagnose a number of exhaust problems based on different engine sounds, a visual inspection of the exhaust is much more reliable way of assessing the condition of the entire system — from the manifold to the tailpipe.
To be able to tell if there’s a problem with the exhaust system, there are a few things that you can watch out for while you are driving your car. Two of the most common signs that the exhaust has been blocked off are reduced gas mileage, as well as loss of overall performance.
What are the symptoms of an exhaust restriction?
The PCM then re-establishes a chemically correct air/fuel ratio by adjusting the weight of fuel to the weight of air flowing through the engine. The symptoms of a ¬restricted exhaust on a MAF-equipped engine will be a noticeable loss of power rather than a rich fuel condition.
What does a positive exhaust pressure reading mean?
Any positive exhaust pressure reading at idle indicates exhaust restriction. Any significant gain in exhaust gas pressure as the engine is accelerated also indicates exhaust restriction.
Which is the best diagnostic test for exhaust restriction?
Consequently, the diagnostic procedure chosen depends very much upon the skill level, system knowledge and tooling of the individual technician. A simple exhaust system backpressure test remains the most reliable method of locating an exhaust ¬restriction.
