Everything You Need to Know About Diesel Engine Overhauls

If your diesel engine is acting up, using more oil than usual, or losing power, you might be wondering whether it’s time for a full replacement or just a diesel engine overhaul. Obviously you want to avoid the high price tag of a brand-new engine, but still a lot of people are unsure about where to start with their decision. But what exactly is involved with an overhaul?

Knowing how a diesel overhaul compares to other repair options can help you make the right investment. You want to do what’s best for your equipment while watching your budget. An overhaul might be the answer!

What Is a Diesel Engine Overhaul?

A diesel engine overhaul is a comprehensive process. It’s designed to restore the engine to like-new condition, and it typically includes disassembling the engine. From there, each part gets cleaned and inspected. Worn components get replaced, and then everything gets reassembled to factory specs. Because of these careful steps, overhauls can address major performance problems and extend the engine’s lifespan by tens of thousands of miles or more.

The exact scope of an overhaul depends on the type of engine and its level of wear. In general, though, you can expect the pistons, liners, bearings, seals, and gaskets to be replaced or refurbished. It’s a cost-effective solution for those who want to protect their heavy-duty trucks, construction equipment, or agriculture machines when replacing the engine entirely isn’t always practical.

The Difference Between an Overhaul vs Rebuild

While many people use the terms interchangeably, there are subtle differences in the overhaul vs rebuild conversation. A rebuild usually involves replacing or reconditioning parts to restore basic functionality. It's typically less extensive and may only address specific failures or worn-out components.

An overhaul, on the other hand, is more comprehensive. It’s meant to bring the engine back to original performance standards, often using OEM or high-quality aftermarket parts. It’s a detailed process and usually includes a complete teardown and inspection. Overhauls are ideal for long-term reliability, while rebuilds can be a quicker fix for engines with less damage.

Both approaches can be solid options for an engine that needs help. But what’s right depends on your engine’s current condition and how you use it. You’ll also want to consider how much more life you want to get out of it. Either way, having the right parts on hand is essential to getting the job done right. That’s how we can help.
