Do you have a Series 60 engine from Detroit? For the most part, it probably runs great for you. This electronically controlled engine has a favorable history, shared between all three versions, and despite having been out of production for years now, it remains a popular choice for many operators.
Continue reading 7 Common Detroit Diesel Series 60 ProblemsIf you’re working on a Cummins ISX15 and run into fault code 0731 (camshaft and crankshaft misalignment) after an overhaul, it can be frustrating.
Especially when:
👉 Yet the code is still active.

A diesel turbocharger is not silent.
A light whistle, whoosh, or spool sound under load can be completely normal. However, when the sound changes suddenly, gets louder, or comes with smoke, low power, or oil consumption, it can point to a problem in the turbocharger system.
The key is not just hearing the sound.
It is understanding what kind of sound it is, when it happens, and what else the engine is doing at the same time.
Turbocharger noise can come from the turbo itself, but it can also come from boost leaks, exhaust leaks, restricted air filters, fuel system problems, damaged exhaust components, or lubrication issues. Garrett specifically notes that noisy performance, low power, smoke, and oil consumption can come from underlying engine problems—not always the turbocharger itself.

If you want solid diesel engine performance, then you need to use your injectors effectively. There’s a specific system your injector uses to improve engine performance: trim codes.

Diesel cylinder head cracking is one of the most serious issues an engine can face – and one of the most expensive if it’s not caught early.
What makes it worse is that it often starts small.
A minor overheating event, a stress point in the casting, or an installation issue can eventually turn into coolant loss, compression problems, and complete engine failure.
Understanding what causes cylinder head cracking – and what to look for – can help prevent repeat failures and unnecessary downtime.
Continue reading Diesel Cylinder Head Cracking: 4 Causes, Symptoms & PreventionThe difference is not just speed.
It is how the engine is loaded, how often it changes state, and how long it stays in stable operating conditions.
City driving introduces:
Highway driving introduces:
These differences directly affect internal engine conditions.

The Caterpillar 3406B and 3406C are known for durability.
But like any diesel engine, they don’t last forever without internal wear.
Over time, compression drops, oil consumption increases, and performance starts to decline.
When that happens, a complete solution like a Caterpillar 3406B, 3406C engine rebuild kit becomes necessary.

The cylinder head on a Caterpillar C15, C15 ACERT, or 3406E is one of the most critical components in the engine.
It controls:
When the cylinder head starts to fail, it doesn’t stay contained. It affects the entire engine.

If your Caterpillar C12 is losing power, burning oil, or showing signs of internal wear, you may be getting close to a rebuild.
And when that time comes, an inframe rebuild kit is one of the most efficient ways to restore engine performance without removing the entire engine.
But knowing when to rebuild – and what’s actually included – makes all the difference.
Continue reading Caterpillar C12 Inframe Rebuild Kit: What It Includes, When You Need It, and How It Restores PerformanceIn trucking, a truck only makes money when it is moving.
When it is not moving, costs do not stop.
👉 Downtime is any period when a truck is out of service and not generating revenue.
This includes:
Even a single day of downtime can have a measurable financial impact.

They are not a single product type. Instead, they are formulated blends designed to address specific fuel system conditions or operating environments.
Depending on formulation, diesel fuel additives may be used to:
👉 The effectiveness of an additive depends on fuel quality, engine condition, and application.

You’ve replaced the injectors.
You’ve programmed the trim codes correctly.
Everything checks out – and the engine still runs rough.
This is more common than most people realize.
Fuel injector trim codes are designed to fine-tune fuel delivery, but they are not a fix-all. If the engine is still underperforming, the issue is almost always outside the trim code itself.
Continue reading Why Correct Fuel Injector Trim Codes Still Result in Poor Engine Performance
