5 Reasons Your Engine Is Making Loud Noises

Some car models are more susceptible than others when it comes to engine issues. That’s why car owners must know the signs of a failing engine. In most cases, an engine making loud noises could signify something wrong with the vehicle. 

This article goes over five of the most common reasons your engine is making loud noises and why you should have it checked by your auto repair professional

1. Exhaust Leaks

A buildup of carbon inside your engine can significantly cause an exhaust leak. A broken manifold, cracked pipe, or loose-fitting will allow gases to escape from the car's system and result in unusual noises. In addition to a noticeable hissing sound, you might notice oil on the outside of your vehicle. 

  • Why you shouldn't ignore it: Exhaust leaks can be dangerous because carbon monoxide is a poisonous gas that you won't know is in your car. If you think you might have an exhaust problem, take your vehicle to your mechanic so they can inspect it for issues and fix it right away. 

2. Engine Misfire

When more than one cylinder is firing in a car's engine, it's known as an engine miss or random misfires. If there is too much fuel in some cylinders and not enough in others, the spark plug on some will fire while another cylinder is still combusting gas. The resulting sound will be like a popping noise. 

  • Why you shouldn't ignore it: Engine misfire can cause a car to run very roughly, and it could even damage your engine in the long term. If you notice a popping noise when starting your vehicle or hear it revving up, take it in for an inspection right away. 

3. Valve Train Noise

The valve train is responsible for opening and closing valves inside the engine. When one of these parts starts to wear out, it will make a clicking sound. This noise is usually heard when starting up a car after it’s been sitting for a few hours. 

  • Why you shouldn't ignore it: Worn-out valves can lead to more significant problems if they aren't fixed right away. It could damage the piston and result in severe engine failure. 

4. Worn-Out Piston Rings

Piston ring problems are usually caused by oil and fuel damaging the cylinder walls and not getting burnt up in the engine's combustion chamber. This can result in excess metal shavings coming from the car, which will fall out of the exhaust pipe as smoke. 

  • Why you shouldn't ignore it: The engine's pistons and cylinder walls will begin to wear away if not fixed. This can result in a bad oil leak or even a significant engine failure. It could also damage other parts, such as the spark plug hole, which could be very expensive to fix. 

5. Cylinder Glaze

A buildup of carbon on the surface of cylinders can cause an engine to make loud noises. This glazing is caused by unburned fuel and oil that eventually hardens on the metal cylinder head instead of turning into exhaust fumes. If not taken care of, it will overheat, damaging other parts. 

  • Why you shouldn't ignore it: Cylinder glaze will cause an engine to become less efficient, which means it could lower your gas mileage. It could also result in other problems related to overheating. 

Get Your Car Checked

Since these five reasons can lead to more significant problems if not attended to immediately, you must take your car in for repairs as soon as you notice something is wrong. Ignoring the problem will only lead to costly repairs and engine replacements.
