Over time, we’ve picked up on some of the most frequent issues that you might face if you’re driving a Ford. While these trucks are hard-working and packed with power, they’re not exactly immune to breaking down. 

While timely maintenance can help you keep your truck out of the shop, we think it’s best you know about common engine problems in Ford diesel trucks so that you can keep an eye out for them. 

Remember, if you put off small repairs, they don’t just go away. They typically snowball into much bigger, more complex and expensive repairs, especially when it comes to your engine

1. Black Exhaust

No one likes to inhale the black smoke coming from a diesel trucks tailpipe, and exhaust is usually the result of an imbalanced air to fuel ratio, too much fuel, not enough air. This could mean a faulty injector, injector pump, air filter, EGR valve, or turbocharger. When it comes to Ford diesel trucks and common engine repairs, this is an issue that you’ll want a TSC Ford Specialist to look into right away.

2. Oil Oxidization

This occurs when trucks sit too long or are not used very often causing air to seep into the oil, which produces bubbles and eventually will not lubricate all the moving parts properly. This will inevitably damage an engine and needs to be changed immediately.

3. Wrong Viscosity Weight

Engine oil with the wrong viscosity will be a major issue for the way your vehicle runs, so consider using a multi-viscosity oil year-round to avoid problems.

4. Bad Fuel

Diesel engines are much more viscous than gas engines, making it more susceptible to contamination. Glycol, dilution, soot, and water are extremely detrimental to your fuel system

5. Humidity

This will also cause water or wetness to contaminate the engine lubricant, and speed up the oxidization process, which will deteriorate the engine life quickly. If you live in a high-precipitation area or have left your vehicle sitting in a wet place, you will need to have it serviced, especially if you hear a knocking sound from the engine. 

6. Unusual Noise

We all know that diesel engines are in general louder than other vehicles, but if you hear knocking or otherwise, have it serviced, as this is not normal.

7. Lead-Acid Storage Batteries Failing

These batteries take a lot of abuse and are essential to a Ford diesel truck. Failing batteries cause an imbalanced compression ratio, which can make the starter system act negatively. 

8. Difficult to Start

One of the more common engine problems in Ford diesel trucks, this is usually a sign of low compression or a fuel delivery issue. You may even notice a delayed start, which should be looked at promptly.

9. Power Problems

Dirty fuel filters, loose throttle linkage, too much lubrication or a fuel injector can cause lack of power when accelerating or starting, relating to a fuel issue.

10. Bad Glow Plugs

Diesel engines rely on glow plugs to ignite the mixtures through a high-resistance heating element, unlike cars which rely on a spark plug. You may find you need to replace these, especially in colder weather.

11. High Compression Ratio

The average compression ratio for a diesel engine is 20:1, making it more powerful and efficient, but it can also cause fuel injection issues from undesirable burn patterns, and you may hear a knock in the engine.
