If your daily car experiences an unusual engine noise, assume there's a problem. This can be identified by the "unusual noise" emitted, and the severity of the symptoms will vary. If you're looking for information on this topic to prepare for a potential emergency, Mr. Worthy has compiled the details for you. Let's dive in!
What causes an unusual engine noise
Let me reiterate that there are many different kinds of engine "audible" warning signals to let you know about impending problems, and each sound indicates a different problem. So, we've listed the different types of sounds to help you better understand them.
Let me reiterate that there are many different kinds of engine "audible" warning signals to let you know about impending problems, and each sound indicates a different problem. So, we've listed the different types of sounds to help you better understand them.
The sound is like metal hitting each other rapidly.
The engine sounds like a loud, rattling sound of metal hitting each other. Although it's not a very loud sound, it's still at a level that can be quite annoying. This sound indicates a malfunction of the valve. If it's an old car, it means that the valve is worn out due to use. However, if it's a new car that was recently purchased or is not very old, it could be because the valve clearance is off.
Heavy knocking sound
If you hear a loud knocking noise from your engine every now and then, it's time to "fix it immediately" because it's a sign that "something in the engine is worn out", causing the car to jerk back and forth, which creates the noise. It's also dangerous for the engine, especially if there's no more engine oil left to lubricate the various systems inside the engine.
Loud noise when turning
If a loud noise occurs in the front wheel area, including when turning the car, assume that there is some abnormality in the "drive shaft", such as a torn axle boot, worn/broken ball bearings, or bearings lacking lubricating grease, causing "grit" that creates annoying noises. It is recommended to fix it immediately to prevent the ball bearings from breaking and causing problems when turning the car.
High-pitched sound
If you've just started your car and a high-pitched noise occurs, it's clear that the belt is old or stiff. When it comes to automotive belts, there are several areas that need to be inspected, including the air conditioning belt, alternator belt, and steering belt. If the inspection reveals that it's too old or stiff, it should be replaced immediately. Furthermore, the replacement belt needs to be of sufficient quality to avoid future problems.
Loud noise when accelerating
When you are accelerating to overtake or using the car normally and a loud "bang bang" noise occurs, I must say right here that the "engine ignition" has a problem. This results in combustion not being as it should be. This symptom can be caused by many things, such as the fuel supply valve, spark plugs, air filter, ignition coil, and distributor. If you are not sure, it is best to take your car to a specialist for a checkup.
Loud noise under the car
While driving on the road and suddenly there is a squeaking sound under the car, don't panic because your car is giving a warning signal. It is recommended that you park the car and look under the car to see if there is anything caught under the car or if any car parts have come loose and scraped the road surface.
If after checking everything, nothing is found to be loose or disconnected, and the noise persists, assume that it may be caused by "movement of the propeller shaft or exhaust pipe" that may be torn, damaged, or otherwise affecting the engine.
Loud noise when falling into a pothole or driving on rough roads
If you're traveling on a rough road and you hear a loud noise from one of your wheels, it could be due to a "broken wheel bearing" or a "worn shock absorber." We recommend replacing the part immediately, as continued use could lead to an accident. Furthermore, replacing this part doesn't take long.
These are just a few of the "warning sounds" you should keep an eye out for. In reality, there are many other types of noises that indicate other potential problems, such as a squeaking sound that indicates a tire problem, or an unusual sound when braking, indicating a problem with the brake pads. Regardless of the warning sound your car is making, getting it checked by a professional is the best option. Don't neglect it!
It's important to reiterate that any noises emanating from your beloved car are "warning signs" that you shouldn't ignore or push problems aside. These noises are often caused by the deterioration of car parts, regardless of their type. While some noises may seem minor, leaving them unchecked or repaired for extended periods can lead to serious problems, potentially leading to unaffordable expenses.
