Why is My Diesel Engine Making Strange Noises?

Stop! What’s That Sound?

Weird Noises Should Never Be Ignored

Diesel trucks are designed to go the distance. However, this doesn’t mean that they’re invincible. As with all other cars and trucks, diesel vehicles must be appropriately maintained. In addition to regular inspections, accurately identifying signs of trouble can help you avoid more significant problems and costlier repairs. While your diesel vehicle might make weird noises every now and then, some of the sounds you should never ignore. These include knocking and pinging noises coming from your diesel engine. If your commercial truck makes these unusual sounds, it could indicate a serious issue.

The diesel truck repair specialists at ARS Truck & Fleet Service in New Castle, Delaware are here to help. Here’s everything you need to know about a knocking diesel engine.

Common Causes

It’s common for diesel engines to make noises. Not every sound coming from under your hood should be considered a red flag. However, if the problem persists or other symptoms accompany the noise, booking an appointment with our ASE-certified mechanics is a smart idea.

A few common reasons diesel engines make knocking sounds include:

• Pre-ignition, which is caused by the air-and-fuel mixture in your cylinder getting prematurely ignited.
• Poorly adjusted valves, low oil levels, or issues with valves and pistons can cause ticking noises in your engine
• Faulty injectors
• Problems with your timing chain, crankshaft, or camshaft can cause meshing noises under the hood

Call the ASE-certified diesel truck repair experts at ARS Truck & Fleet Service in New Castle, Delaware, if you hear any of these sounds. With years of experience, our team of master mechanics can properly diagnose the noises and make the necessary repairs as quickly as possible.
