On a Cummins N14, fuel injectors are one of the most critical components controlling engine performance.
They don’t just deliver fuel – they control timing, atomization, and combustion efficiency.
And when they start to fail, the issue doesn’t stay isolated to one cylinder. It begins to affect engine balance, temperature, and long-term durability.
Continue reading Cummins N14 Fuel Injectors: How They Fail, What It Affects, and When to Replace ThemHow do you pick the right diesel engine model? This is a challenging task. You’ll need plenty of information if you’re deciding between the Caterpillar 3406E, C15 ACERT, or C15 engine. And we have as much information as you can get to make an informed decision.
Continue reading Important Differences Between Caterpillar 3406E, C15, and C15 Acert Diesel EnginesEGR systems are a standard part of modern diesel engines – but they are also one of the most common sources of frustration.
These systems are designed to reduce emissions and meet EPA regulations. However, they also introduce additional components that operate under high heat, pressure, and contamination.
Over time, this combination can lead to performance issues, costly repairs, and system failures.
Continue reading Problems with EGR Systems in Diesel EnginesWhen a head gasket fails, most people look at the gasket.
But in many diesel engines, the real issue isn’t the gasket at all: it’s improper clamp load caused by incorrect bolt stretch.
If clamp load isn’t correct or consistent across the cylinder head, combustion pressure will find a way out.
This is where understanding bolt stretch vs. torque becomes critical.
Continue reading Cylinder Head Bolt Stretch vs Torque: Why Your Head Gasket Keeps FailingAre you looking to replace the fuel injectors on your CAT 3406E, C15, or C15 ACERT diesel engine? If so, it’s probably fair to assume that you want the best quality, highest functioning injectors you can get. And, if you’re spending money on quality injectors, you want them to work correctly.

It’s a sign of imbalance. In a diesel engine, imbalance means:
The important part is understanding why that one cylinder is different.
Continue reading Why One Diesel Cylinder Runs Hotter Than the Others (And What It Means)You’ve just been told that you need to replace your diesel engine fuel injectors, but what exactly caused the failure that led to this point?
Continue reading Diesel Engine Common Rail Injectors: Potential Failures & CausesLubrication is key to keeping your engine functioning properly. If your diesel engine isn’t properly lubricated, components could begin to wear more quickly and even seize up, costing you more money. The oil pump is critical to keeping your engine lubricated.
Continue reading Problems You Might Have with Your CAT C15 ACERT Diesel Engine Oil PumpWe all know that the head gasket is important. It’s what creates the seal between the engine block and cylinder head to allow for combustion to happen. Without it, your diesel engine won’t run properly.
Continue reading What Problems Indicate Head Gasket Failure on C15 ACERT Diesel Engines?As you probably know, one of the main differences between the Caterpillar C15 diesel engine and the C15 ACERT is the fact that the ACERT is designed with two turbochargers. That makes this component even more vital to the overall function and health of your diesel engine.
