Not all engine noise is the same.
A ticking sound and a knocking sound may seem similar, but they point to very different issues inside your diesel engine.
In many cases, both originate in the valve train system – and both can escalate into major engine damage if ignored.

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.

Belt noise on a diesel engine is not just an annoyance.
It is often an early warning sign of misalignment, bearing failure, or improper belt tension.
Ignoring it can lead to:
Proper diagnosis requires understanding how the belt system operates under load.

The cylinder head on a Caterpillar C10 or C12 isn’t just a casting – it’s where combustion, airflow, and cooling all come together.
And when it fails, it usually doesn’t fail quietly.
Cracked heads, worn valve seats, and injector cup issues are some of the most common – and most expensive – problems we see on these engines. If you’re already chasing coolant loss, misfires, or compression issues, there’s a good chance the cylinder head is involved.

If you’ve ever dealt with a diesel fuel system issue, you know how quickly things can escalate. What starts as a minor problem – like a slight misfire, rough idle, or extra smoke – can quickly turn into major engine damage if it’s not addressed early.
That’s what makes modern diesel fuel systems so challenging.
They’re not just sensitive – they’re precise to the point where even small disruptions can create serious problems. When something in the system changes – even slightly – it directly impacts combustion. If you’re already dealing with fuel system issues or looking to prevent them, you can explore our full range of diesel fuel system components designed for reliability and performance.
Continue reading Why Diesel Fuel Systems Are So Sensitive (And How Small Issues Turn Into Major Repairs)Detroit Diesel history is one of the clearest examples of how diesel engine technology has evolved over time.
From early two-stroke engines to today’s electronically controlled platforms, Detroit engines have powered trucks, buses, military equipment, and industrial machinery for decades.
This timeline walks through the major Detroit Diesel engine families in chronological order.

When Caterpillar stopped producing on-highway diesel engines in 2010, it didn’t mean those engines disappeared.
In fact, thousands of Caterpillar engines – especially the C15 – are still running today in fleets across the country.
So the real question isn’t just why Caterpillar left the market.
If you’re looking for a full breakdown of that decision, read Why Caterpillar Stopped Making On-Highway Diesel Engines to understand the emissions, engineering, and business factors behind it.
👉 It’s what that decision means for reliability, parts availability, and long-term ownership today.
Continue reading What Happened After Caterpillar Stopped Making Truck Engines (And What It Means for C15 Owners Today)Do 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.

Dirty or clogged diesel fuel injectors are one of the most common – and most misunderstood – fuel system problems.
A lot of people think it’s just a restriction issue. Spray some cleaner, maybe swap a filter, and you’re good to go.
But in reality, injector contamination leads to precision failure inside the injector itself – and once that starts, performance drops fast.
Before you try a quick fix, it’s important to understand what’s actually happening inside your injectors.

The oil pump in your Detroit Diesel Series 60 isn’t just another component – it’s the heart of your lubrication system. When it starts to fail, the damage doesn’t stay isolated. It spreads fast.
Low oil pressure, bearing wear, and even full engine failure can all trace back to one root issue: inconsistent oil delivery.
If you’re working on a Series 60, understanding how the oil pump fails – and how to catch it early – can be the difference between a simple repair and a full rebuild.
Continue reading Detroit Diesel Series 60 Oil Pump Failure: Causes, Oil Pressure Loss, and When to ReplaceA breakdown while driving isn’t just inconvenient – it can be dangerous if handled wrong.
Whether it’s loss of power, overheating, a blown tire, or warning lights across the dash, what you do in the first few minutes matters most.
This isn’t about panic.
It’s about control, visibility, and safety.
Diesel engine overheating is one of the most common – and most damaging – issues you can face.
What starts as a slight temperature increase can quickly turn into major engine damage if not diagnosed correctly.
If your diesel engine is overheating, identifying the root cause early is critical to preventing expensive repairs and downtime.
