Causes of a Rough Car Engine Sound and How to Overcome It

The sound of a rough car engine is certainly very annoying when used. From the sound, there is concern that the car's engine is having problems. If left alone, there could be a problem with the car's engine.

If this sound is left unchecked, it can cause other components in the car engine to be damaged. Therefore, when your car engine sounds rough, you should immediately check it so that there are no bigger problems.

There are several factors that cause rough car engine sounds that you need to know so that it is easy to find a solution. Sometimes it is even found when the car is started at low RPM. The following is a review of the sound of a rough car engine, which you can see below.

Causes of Rough Car Engine Sound

BAlmost the same as the sound of a rough car engine when it is started, sometimes a car engine at low RPM can make a rough sound. The sound of a rough car engine at low RPM is caused by a gap in the car engine valve. These gaps have their respective standard sizes; if they are too tight or too loose, they can cause a rough sound.

Of course, you have to know several other factors to find out the cause of a rough car engine sound. So that later you can avoid the sound of a rough car engine in your favorite vehicle. The following are the causes of a rough car engine sound:

Lack of Engine Oi

It should be remembered that a lack of engine oil volume in a vehicle will not only cause a rough car engine sound when running on gas or damage to the AC compressor, but will also cause many other problems.

Oil that is dirty and rarely changed is the cause of this oil volume decreasing. You can check the quality and volume of oil by looking at the dipstick on the tank. Pay attention to the quality and color of the oil, adjust the dosage, and make sure the oil is not mixed with other liquids or has dirt stuck to it.

This must be done regularly to ensure that the oil, as a lubricant for car engine components, functions properly. Apart from that, don't forget to use quality engine oil according to the manufacturer's recommendations so that the car's engine lasts longer.

Problems with the AC Compressor 

If you hear a harsh sound from the car engine when you press the gas pedal, there could be a problem with the AC compressor. This kind of sound can occur when the car is started or has been running, and this happens because the AC compressor is low on oil. Therefore, oil that is rarely changed causes dirt to accumulate, which can ultimately clog various engine parts.

Problems with Engine Valve Gaps 

Problems with car engine valve gaps can cause a rough car engine sound when pressing the gas. Valve gaps that are too tight or loose can cause the car engine to sound harsh when driven. This gap usually measures between 0.2 and 0.3 mm.

However, if the vehicle is used more frequently, this gap can loosen and produce a sound like metal rubbing due to the valve stem rubbing against the rocker arm. The same thing applies when the gap is too tight because the valve stem is pressing on other parts of the valve.
