Today we’re going to go over a little bit about cylinder heads. Before diving head first into the cylinder head market, its important to have an understanding of what you’re working with.
Continue reading How Does a Cylinder Head Work On A Diesel Engine?Is It Camshaft Lobe Wear Or Damage? We all know how important camshafts are to the function of your diesel engine, and when they fail it can spell big trouble. Whether you have a flat tappet or a roller camshaft, you’re at risk for one of the most common causes of camshaft issues: lobe wear or damage.

Having problems with your Caterpillar C15? A new engine rebuild kit from Highway and Heavy Parts may be just what you need!
Your Caterpillar C15’s power and reliability start with the core parts deep inside the engine, where compression, cooling, and lubrication all come together. Over time, those internal components – pistons, liners, rings, and bearings – wear down and slowly lose their ability to seal, cool, and support the engine the way they should. Once that happens, you’ll start to see blow-by, oil consumption, fuel dilution, rising temperatures, and a noticeable drop in performance.
The longer those issues are ignored, the faster they snowball into bigger problems like scored liners, damaged pistons, or even a complete engine failure. That’s why a complete engine rebuild kit is so critical for a C15. Replacing everything at once restores the engine’s foundation, brings compression back to spec, and stops small issues from turning into expensive downtime.
Not sure if it’s time for a rebuild? Look for these warning signs:
Waiting too long allows minor wear to cascade into major failures, but acting now can save thousands in repair costs.

If you work around diesel engines long enough, you’ll start to recognize the same names.
Across trucking, construction, agriculture, marine, and power generation, a group of manufacturers has built engines designed to handle load, heat, and long hours.
This guide is a simple overview of the major diesel engine manufacturers around the world – what they build and where you’ll see them.
Cummins produces diesel engines for on-highway trucks, industrial equipment, and power generation.
You’ll commonly see them in:
They are widely used due to broad support and application range.
Caterpillar engines are built for high-load applications like construction, mining, and marine.
You’ll find them in:
These engines are known for durability in demanding environments.
Detroit Diesel focuses on on-highway truck engines.
You’ll find them in:
They are designed for consistent highway performance and emissions integration.
Volvo builds diesel engines for trucks, construction equipment, and marine use.
They also produce engines for:
Their engines focus on integrated systems and efficiency across applications.
Scania produces diesel engines for trucks, industrial equipment, and power generation.
They are known for:
FPT Industrial manufactures diesel engines for:
They focus on multi-application engine platforms.
Deutz specializes in compact diesel engines used in:
Their engines are known for simple, durable designs.
MTU engines are used in high-performance applications like:

No matter the size or application, these engines are built around the same fundamentals:
The design may change: but the goal stays the same:
👉 Keep equipment running reliably in real working conditions.
Knowing the manufacturer helps you understand:
Because the same issue – like loss of power or overheating – can have different causes depending on the engine platform.
There’s no single “best” diesel engine manufacturer.
Each one is built for a specific purpose.
What matters is:
Because in diesel engines, reliability comes down to understanding the system – not just the name on it.
