Why Is My Engine Making Weird Noises?

Hearing a strange noise coming from your vehicle is almost never a good sign, mainly if it is happening under the hood of your car. You might be concerned, which is good, as long as you never brush it off. The problem can be as simple as a loose component, or it could hint at something much more severe. If the noise comes from the engine, it can mean different things. Here are some of the most common types of noises that your engine may make and what they imply: 

Clicking Noise

A clicking noise that emits when you rev the engine is usually a symptom of low oil pressure, excessive valve wear, or worn or damaged engine components. It's best to have your engine and oil checked out and pinpointed by an auto technician.

Pings or Knocks When Accelerating

A pinging or knocking sound that is heard during acceleration can be caused by various things, including ignition timing issues, engine overheating, carbon buildup, or too low octane fuel

Low Rumbling or Knocking Sound

If you pick up a low rumble or knocking sound when the engine is warmed up, you likely have a defective rod bearing on the crankshaft. If neglected, the bad part can worsen by leading to bearing failure, rod breakage, or other crankshaft damage.
