🚧 Is your XCMG excavator throwing codes or losing power on the job site? 🚧

An idle machine doesn't just mean a delay, it's a massive hit to your daily revenue. If you’re running XCMG XE-Series excavators (like the XE210U, XE235UCR, or XE250U) powered by a Cummins 6.7L, ignoring your dash lights can lead to catastrophic internal damage.

In our latest blog post, we break down the most critical fault codes you need to watch out for.

Rusted factory freeze plugs are a ticking time bomb on a 7.3 Powerstroke. 💣

Upgrading to billet freeze plugs removes a notorious OEM weak point, giving you permanent cooling system reliability whether you're daily driving or pulling heavy trailers. Check out our latest guide to see why this small change makes a massive difference in safeguarding your engine.

Why Billet Freeze Plugs are a Must-Have Upgrade for the 7.3 Powerstroke Diesel The 7.3L Powerstroke diesel engine is known for its durability and longevity. But if you're building for reliability, towing regularly, or adding performance mods, one small but critical upgrade often goes overlooked: the...

We wouldn’t have used this engine block, even in one piece. 🛠️

Seeing a rod try to escape the block is always wild, but this kind of failure isn't actually why we skip the 2019+ Cummins blocks for our crate engines.

Our decision to completely avoid the 2019+ platform comes down to factory design changes that just don't align with heavy-duty performance and longevity. We build for ultimate reliability, which means knowing exactly which block geometries and materials to trust, and which ones to leave behind.

If you want an engine built without the factory compromises, you have to look past the model year.

Why we throw away OEM 12v Cummins valve SEALS 🗑

Factory seals rely on a tiny band to grip the guide. Once that band loses tension, the seal loses its grip and starts traveling up and down with the valve, allowing oil to bypass the guide.

Our fix: Top Hat style Valve Seals

The base of this seal sits directly under the valve spring, physically pinning the seal in place. No more traveling seals, no more oil bypassing the guides.

👇 Have you found loose, traveling seals on your 12v teardowns?

🚨 HYPED TECH OR REAL POWER? 🚨

We're preparing to settle the debate the only way we know how: on the dyno. 📈

We are setting up a strict back-to-back A/B test pitting a set of dimples "Speed of Air" pistons against standard OEM pistons. The marketing promises reduced emissions, increased performance, and higher fuel mileage.

We have our doubts. 🧐

Can a bunch of golf-ball style dimples actually change the game inside a combustion chamber, or is it just clever marketing? We're about to find out exactly what the data says.

👇 Drop your predictions in the comments: Real gains or pure hype?

Stay tuned for the final numbers.

Rocker arm failure on a 6.4L Powerstroke? No thanks. 🛠️

Factory valve covers leave your upper engine starving for oil when you push it hard. Upgrading to self-oiling valve covers is the ultimate way to deliver constant lubrication to your valvetrain and keep your engine alive for the long haul.

Find out why this simple change makes a massive difference in preventing catastrophic wear.

Read the blog post: https://choateperformance.com/blogs/blog/protect-your-investment-why-self-oiling-valve-covers-are-essential-for-your-6-4l-powerstroke

Your 6.4L is slowly self-destructing due to oil starvation on startup without this special part. Check out our solution that delivers instant lubrication!

Is a poorly balanced crankshaft secretly holding your truck back?

When people chase down a loss of power, they look at turbos, injectors, and tuning. But if your bottom end isn't balanced, you’re fighting a losing battle from the inside out.

🚧 Yellow iron belongs on the job site, not sitting idle in the shop. 🚧

If you are running Komatsu equipment powered by the SAA6D107E engine (like the PC200-8 excavators or WA250 wheel loaders), you know these powerplants are built to work. But under constant hydraulic load and dusty site conditions, failure to address warning lights early can lead to catastrophic internal damage and massive hits to your daily revenue.

In our latest blog post, we break down the most common failure points and fault codes hitting the SAA6D107E platform.

"Nothing stops a job site faster than a PC210 excavator or a WA320 wheel loader flashing a fault code and dropping into 'Limp Mode.' At the heart of these machines is the Komatsu SAA6D107E, a 6.7L workhorse built on the Cummins QSB6.7 platform." While it is one of the most reliable engines in the wo...
