There are many popular car exhaust problems that do not require you to visit a mechanic. It is important to identify these problems early in advance because if they go on for long they may lead to engine problems and this because the exhaust main purpose is the removal of harmful elements from the engine. If you fail to identify these problems early you may end releasing dangerous carcinogens in the air. Inspecting for car exhaust problems on a regular basis is very important and this includes the search for cracks or fissures that are affecting the exhaust system.
If you think that your pipes are corrodes you should poke them using a screwdriver to see if they give in they are supposed to be replaced. The muffler should also be replaced if it appears not to be solid or shinny. The tailpipe is the only place the smoke from the engine should come from. The exhaust fumes are mostly colorless as well as odorless and they pose a lethal threat and this is because they affect the perception and judgment of the driver and this is why the cracks should be checked on a regular basis. You should know there is something wrong with your exhaust system when you hear a hissing or popping sound from the engine.
These sounds normally indicate that pipes or the muffler are leaking. For the vehicles that have 4 cylinder engines they usually have harmonic resonance and this is due to exhaust problems which will produce a bussing noise. These problems can be rectified by turning the system which will dampen the noise. Most of these vehicles have user manuals where there is information on how to do this. If this noise persists you should then install a resonator or a second muffler. Exhaust restriction is another common car exhaust problem and this is as a result of using too much fuel or if the car is losing power.
The most common causes of exhaust restriction are damaged or crushed piped bafflers that have collapsed inside a resonator or a muffler or a catalytic converter which is plugged. To restore this problem is to go to the root of the problem and this includes unplugging of the catalytic converter only if it is a plugged catalytic converter problem. For you to know if you have an exhaust restriction problem you are supposed to go through the engine's manifold vacuum only when the car is idle. The figure should always be over 18 inches. Another common problem is the exhaust backpressure.
The backpressure should be regularly measured and one way of doing this is using a pressure gauge to replace the check valve. This should always be below 1.5 psi and anything more than 3 psi will indicate restriction problems. This can also be rectified by removing the exhaust manifold's oxygen sensor through replacing it with an adapter on where you will mount a pressure gauge. Some cases of ignition misfire or leaky exhaust valves cause plugged converter which is another exhaust system problem. This can be rectified by replacing the plugged converter. These are just some of the various ways of how to fix common car exhaust problems.
