Stay On The Road And Maximize Your Service - Signs Your Diesel Engine Needs Repair

Posted on

When most people decide to purchase a vehicle with a diesel engine, it's because they anticipate working in difficult conditions and needing an engine that can stand up to the associated wear and tear. Because the working conditions tend to be so rough, it's essential that you stay ahead of the curve in terms of repairs and remain prepared to handle any eventuality.

Below, you'll find a guide to some signs that your diesel engine is in need of service. Staying alert for these signs will allow you to avoid lengthy downtimes and costly repairs, and can help guarantee that you get the performance from your engine that you envisioned when you made the original purchase.

Loud Noises

Most diesel engines run louder than their standard counterparts, but some sounds are still important warning signs. If you operate a vehicle every day, you're going to be more accustomed to its standard sounds than most people, and staying alert for deviations from the norm is an important task to complete.

If you notice your exhaust or engine block producing sounds that seem louder than normal or at an unusual pitch, it could be a sign of a serious pending mechanical failure. Having your engine inspected at the first sign of trouble is an important step in preventative maintenance that can help guarantee a successful repair.


Diesel fuel produces somewhat different byproducts than standard gasoline, and operators of diesel engines are likely to be familiar with the particular odors associated with that. When those odors change or clouds of smoke become visible, it's likely a sign that something has gone wrong.

If your engine ever begins to emit smoke as opposed to standard exhaust, it could be a sign of serious overheating or insufficient lubrication in your piston assembly. Addressing these issues in a timely fashion is important if you want to dodge the potential of a complete engine teardown.

Difficulty Starting

When a starter in a diesel vehicle fails to fire easily and smoothly, it can be a sign that your fuel system is sluggish and in need of clean out or repair. If enough fuel doesn't reach your engine, your starter won't be able to turn it over, and you'll struggle with operating your vehicle. At the first sign of starter difficulty, having the problem diagnosed could allow you to resolve it through the use of fuel additives and other simple solutions rather than relying on an intense mechanical teardown.
