Common mechanical problems with Repairing diesel engines

Diesel motors have different priorities for preventative maintenance, but it’s all too common for truck owners to put off repairs like any vehicle.

As a result, these are the most common mechanical problems with diesel engines:

The last point deserves a particular word of caution before visiting a diesel repair shop. Warning: Never use ordinary motor oil in a diesel engine!

Using the wrong type of oil will ruin the entire engine because diesel oil has a lower viscosity (i.e., higher thickness) and lasts longer. Sometimes, a used and battered diesel engine will require a full rebuild or wholesale replacement of critical parts. Combine that with the higher than average cost per part, and it’s easy to see why you need to stay on the safe side and find a quality diesel repair shop.

What's the benefit of finding a diesel mechanic?

less shop visits

You’ll need a diesel specialist sooner or later, but the most significant benefit of owning a diesel-powered truck is that you’ll need to take it to the shop less often. The downside is that diesel engine parts cost more overall. You can’t simply swap a piece intended for a gasoline engine and install it in a diesel motor.

diesel mechanics shortage

There is a sharp distinction between compression-based ignition and gasoline-based ignition. You’ll need to know the subtle differences. Also, there is a shortage of certified, trustworthy diesel mechanics across the country. Thus, a diesel specialist commands a higher price tag for their skills and expertise.

Costs

A diesel truck mechanic tip: Stick to a tight maintenance schedule because diesel repair costs more per job.

Comparing diesel engines versus gasoline engines

Not everyone knows the difference between diesel repair and gasoline engine repair. For those who don’t know the distinctions, here is a short breakdown of essential characteristics.

Characteristics of diesel motors:

Diesel engines are typically bigger, louder, and emit more pollution than standard gasoline-powered motors. At a glance, you might be asking yourself, “then why would I want a diesel in the first place?” The answer is that they’re less expensive to maintain over time when you do need diesel repair, and they have more power. A quality diesel repair shop knows that diesel motors require more robust parts and feature better performance when it comes to torque power and fuel efficiency.

The chemical composition of diesel fuel yields more power per gallon, so that’s one reason why diesel-powered trucks make the best work vehicles and need less diesel engine repair.

Characteristics of gasoline motors:

On the other hand, gasoline motors will require a shorter maintenance schedule, meaning that the engine wears down faster, and you’ll need to find a reliable diesel repair shop more often. Gasoline ignition relies on spark plugs to crank the motor; diesel engines use glow plugs for compression ignition.

The result is that gasoline-powered motors produced less toxic emissions than diesel motors. The trade-off is that gasoline gets you less mileage per gallon. Depending on the model of truck you own, the difference in fuel efficiency may be slight but will pay dividends over time when you need less diesel repair.

Ordinary mechanics know their way around any gasoline engine, but a diesel mechanic knows his way around a diesel engine just as well.
