Cylinder head resurfacing is one of the most critical steps in a diesel engine repair – but it’s also one of the most misunderstood.
Resurfacing isn’t just about making the head “look flat.” It’s about restoring the correct sealing surface for combustion pressure, coolant passages, and oil flow. If done incorrectly – or skipped entirely – it can lead to immediate or repeat failure.

Fuel economy in a diesel engine isn’t just about driving habits – it’s controlled by combustion efficiency, fuel delivery accuracy, air management, and mechanical condition.
If one of those systems is off – even slightly – you’re burning more fuel than you should.
This guide breaks down five technical areas that directly impact fuel economy, and what’s actually happening inside the engine when they’re not right.
Continue reading 5 Technical Ways to Improve Diesel Engine Fuel Economy (Without Guessing)Are you able to tell the difference between run-of-the-mill aftermarket parts and quality aftermarket parts? Sometimes it’s hard to discern the difference.
Continue reading Are the OEM Diesel Engine Rebuild Kits Worth It?
A diesel cylinder head does far more than “sit on top” of the engine.
It is a structural, thermal, and airflow control component that directly impacts:
Every combustion event in a diesel engine depends on how well the cylinder head controls air, fuel, pressure, and temperature.

But alignment is not just about steering feel.
It directly affects:
On older trucks, alignment becomes even more important because component wear has already introduced variability into the system.

When a turbocharger fails, the damage is often concentrated in one place:
The center housing rotating assembly (CHRA).
This is the core of the turbocharger – and in many cases, replacing it is the most efficient way to restore performance.

When it comes to diesel engine parts, one of the most common questions is: why are OEM parts so expensive?
Many assume higher cost means higher quality – but that’s not always the case. In reality, the difference between OEM and aftermarket parts often comes down to manufacturing, distribution, and how the parts reach you.
If you’re comparing options right now, you can shop diesel engine parts to find high-quality components built for your specific engine and application.
Understanding that difference can help you make a more informed – and more cost-effective – decision when it’s time to repair your engine.

When diagnosing valvetrain issues in a diesel engine, rocker arms are often overlooked.
But on engines like Cummins ISX, Detroit Diesel Series 60, and Caterpillar platforms, rocker arm assemblies – and more specifically the pin and roller components – are critical wear points.
Understanding the difference between replacing a full rocker arm versus servicing pin and roller kits can prevent repeat failures and unnecessary downtime.
Continue reading Diesel Engine Rocker Arms vs Pin and Roller Kits: What Actually Wears Out and Why It Matters
When a turbocharger fails, most people ask the same question:
Should you rebuild it with a cartridge (CHRA), or replace the entire turbo?
The answer depends on what actually failed.
And getting that wrong can cost you more than the turbo itself.
Continue reading Should You Replace the CHRA or the Entire Turbocharger? What Diesel Owners Need to Know
If you’ve ever tried to compare diesel fuel pumps, you’ve probably run into the same problem:
👉 Plenty of brand names
👉 Almost no clear explanations
If you’re in sales, diagnostics, or repairs, you’re expected to understand:
This guide breaks it down in a way that actually makes sense.

The Cummins ISC-G is not just a diesel engine running a different fuel.
It is a spark-ignited natural gas engine, and that changes how the cylinder head is designed, how it wears, and how it fails.
If you treat it like a diesel cylinder head, you will miss critical differences that directly impact performance and longevity.
Continue reading Cummins ISC-G Cylinder Head: What Makes Natural Gas Cylinder Heads DifferentDo you own a Detroit Diesel Series 60 engine? It probably runs well for the most part. All three versions of this electronically-controlled engine have a favorable reputation; despite being out of production for years, the Series 60 remains a popular choice for many truck drivers.
