Not every engine failure starts with a major event.

This LML Duramax came into the shop with a cracked piston, a failure we commonly see when excessive oil temperatures become a long-term issue. Once temperatures get out of control, internal engine components can take a beating.

The solution? A complete engine replacement.

While we were in there, we upgraded the truck with a Fleece CP3 conversion and a 2020+ L5P oil cooler to improve reliability, fuel system performance, and temperature management moving forward.

Sometimes the best repair is also an opportunity to make your truck stronger than it was before.

Nothing like a little dashboard greeting to start the day.

Diesel owners know the feeling: one minute you’re heading out like everything is normal, the next minute your truck has decided it would like some attention.

Good morning, indeed. 😅

A lift pump is one of the most commonly discussed diesel upgrades—and for good reason.

Its job is simple: provide a consistent supply of fuel to the engine's high-pressure fuel system. By maintaining fuel flow and pressure, a quality lift pump can help support fuel system performance and reduce strain on factory components.

Whether you're towing, daily driving, or building a performance truck, it's an upgrade many diesel owners consider.

Have questions about lift pumps or whether your truck would benefit from one? Give us a call.

If you've spent any time in the diesel world, you've probably heard people talking about CP3 conversions.

The CP4 and CP3 are both high-pressure fuel pumps, but they use different designs and have different strengths depending on the application.

That's why many diesel owners choose to learn about their options when planning repairs, upgrades, or long-term ownership.

Whether you're researching a future upgrade or just trying to understand the differences, knowing what each system was designed to do is a good place to start.

We're grateful for customers who trust us not just when the work is done, but years down the road. Thanks, Jess, for trusting us with your Duramax and for your continued support.

That's the goal every time a truck leaves our shop.

A lot of major engine failures don't start with a bang.

They start with something small:

• A slight miss at idle�
• A little more smoke than normal�
• Temperatures creeping higher than usual
�• A truck that just doesn't feel quite right

The problem is that many owners get used to these changes and keep driving until a minor issue becomes a major repair.

If your truck is acting differently, it's worth getting it checked before the problem gets worse. Catching issues early can save thousands in repairs and a lot of downtime.

It starts with one little noise.

And suddenly you’re wide awake like this guy, wrench in hand, ready to diagnose every possible diesel problem at 2:00 AM.

You’ve priced out parts, watched 17 YouTube videos, convinced yourself the repair will cost more than the truck, and somehow still haven’t slept.

Diesel ownership isn’t just a hobby.

It’s a full-time mental commitment. 😅

What’s the longest you’ve spent overthinking a truck problem before finding out it was something simple?
