A common issue that is found in diesel engines might cause some stress for new drivers – unknown noises. Because of the way diesel engines are built and function, they are know for being noisier than their gasoline counterparts. But not every noise that your diesel engine will make should be a cause for concern, as they are normal for your engine. So before you bring your car to the mechanic, here are some common diesel noise problems and what you should do about them.

Diesel Engine is Knocking

This a common sound caused by the injectors, and if working well the sound should dissipate within a few minutes of the vehicle running. If the sound persists, however, that could be a sign that your diesel engine is in need of new injectors, so keep an ear out for this sound and how long it happens to your vehicle to know if your car needs service.

Hearing Rattling Sounds

Another common noise that happens with your diesel engine is a rattling sound. This usually happens when you’re accelerating, caused by air and fuel mixture in the cylinder getting ignited prematurely by the compression in the engine.

The Engine is Ticking

A ticking noise caused by your diesel engine is an indicator you should take your ride in to see a trusted mechanic, as it could be a sign of a few different vehicle issues, such as low oil levels, rod knock, or poorly adjusted valves.

There is a Timing Chain Meshing Noise

The timing chain is what connects the camshaft to the crankshaft, which is why it’s important to keep it well maintained. When you have a bad timing chain, the noise that you should look out for is a rattling noise when your car is getting warmed up, and a toned down one when the engine is fully running. This noise is common in diesel engines, but it should be taken care of by a professional as soon as possible to prevent further issues.
