If you own a diesel-operated vehicle, you know the power that lies under the hood. However, just like other engines, these heavy-duty trucks have some issues that only a mechanic can remedy. To avoid the most common diesel engine problems, use the following guide.

3 Common Issues With Diesel Engines

1. Smokey Exhaust

One of the tell-tale signs of an old, diesel-run vehicle is the thick black smoke that trails from the exhaust pipe. However, this isn’t a normal byproduct of diesel engine operation. The thick, foul-smelling exhaust means there’s too much fuel and not enough air being fed to the engine. This is usually the fault of a malfunctioning injector, injector pump, or exhaust gas recirculation valve.

2. Dirty Fuel

Compared to gasoline, diesel fuel is much thicker. As a result, it’s easy for contaminants to get stuck in the liquid. Unfortunately, the engine only accepts diesel, not the pollutant stow-aways. If water, soot, dirt, or chemicals are forced to run through the engine anyway, you might experience overheating, or a sudden breakdown.

3. Oxidized Oil

Just like all other engines, diesel engines rely on oil to lubricate the moving parts inside. If a diesel vehicle is out of operation for too long such as trucks put in seasonal storage, it’s possible for air to sneak into the engine. When the oxygen mixes with the oil, it dilutes it, creating pockets of air with no lubrication. If the oil isn’t changed before the vehicle is taken out of storage, it could undergo permanent engine damage.
