Hearing Noises From The Engine? Here's What It May Be

One of the most common concerns for car owners is mysterious noises emanating from the engine. 


When it comes to your car's engine, it is essential to understand the potential issues causing these sounds and why you should turn to the professionals for help. If you're hearing unusual noises from your engine, keep reading to gain some insight and know when it's time to schedule an appointment with us.

Car Engine Noises: The Unwanted Symphony

Your car's engine is the heart of the vehicle, and any unusual noises coming from it can be quite disturbing. It's essential to diagnose these sounds early to prevent more severe issues and expensive repairs down the road. Let's explore some everyday engine noises and what they may indicate.

Knocking or Pinging Sounds:

One of the most dreaded noises you can hear is a knocking or pinging sound from your engine. This sound is often associated with a problem called "engine knocking." Engine knocking can be caused by various factors, including low-quality fuel, carbon buildup, or issues with the ignition system. It's crucial to address this issue promptly because prolonged engine knocking can lead to severe engine damage.


At Placentia Super Service, our experienced technicians can diagnose the cause of the knocking sound and recommend the necessary repairs or maintenance to ensure your engine's health.

Whining or Whirring Sounds:

If you hear a high-pitched whining or whirring noise, it could be related to issues with the accessory drive belt or pulleys. These components are responsible for powering various accessories like the alternator, power steering, and air conditioning. When the drive belt or pulleys are worn or damaged, they can produce these annoying sounds.


Our team at Placentia Super Service is well-versed in belt and pulley system diagnostics and replacements. We'll quickly identify the issue and provide the right solution to eliminate those distracting noises.

Rattling or Tapping Sounds:

Rattling or tapping sounds are often associated with problems in the valvetrain, such as worn-out lifters or a faulty timing chain. These sounds can indicate that it's time for a comprehensive inspection and repair. Ignoring valvetrain issues can lead to decreased engine performance and efficiency.


Our expert technicians can assess the valvetrain components, pinpoint the source of the problem, and execute the necessary repairs with precision, ensuring your engine runs smoothly.

Hissing or Sizzling Sounds:

If you hear any hissing or sizzling noises, it might indicate an issue with the cooling system. A leak in the radiator or a damaged hose can cause a loss of coolant, causing your engine to overheat. It's crucial to address cooling system problems promptly to prevent engine damage and potential breakdowns.


At Placentia Super Service, we specialize in cooling system repairs and maintenance. We'll identify the source of the hissing sound and take the necessary steps to keep your engine running at the right temperature.
