Engine Noises That Require Immediate Attention

Mark Kennedy • May 10, 2022

Engine noises are something every car owner needs to be familiar with. If you can pick up what engine noises indicate, you can quickly have your engine fixed if needed and prevent costly damages or fatal accidents. Here are some of the most important engine noises to listen for.


Knocking Noises


Listen for low or deep knocking sounds. A deep knocking noise needs immediate attention as it indicates a problem in your engine. Knocking sounds means you have a part in your engine that is worn out. You need to take care of this as it can become a worse problem later especially when you try to accelerate. 


Clicking Or Ticking Noises


Some clicking or ticking is good, while others can indicate a serious issue. A low, occasional clicking and ticking isn’t a big deal. Certain engine parts such as your timing belt, chains, gears, and camshaft can cause ticking noises. If ticking and clicking become louder, however, this is a sign that your engine parts are worn out. Worn-out parts can cause a serious problem later on or lead to engine failure so it’s best to have this look at ASAP.


Noises While Accelerating


It’s ok to hear noises now and then but if you hear noises only when you accelerate, it’s time to pay attention. They may be small but these noises can start to increase when you hit the pedal later on. The noise will start to produce a vibration or jerking sensation in your pedal. All of this indicates issues with the engine that could slowly lead to costly issues if not addressed promptly. Have your engine compartment checked the next time you have an oil change.


Now that you know what to listen out for, you are going to need a professional to diagnose and take care of your engine to avoid serious damage. Luckily, here at
