⚠️ 6.7 CUMMINS OWNERS: WATCH FOR THESE VGT TURBO SIGNS ⚠️

The Variable Geometry Turbo (VGT) on your 6.7 Cummins is a great system when it’s working properly—but over time soot buildup and actuator issues can cause problems.

Common symptoms include:

🔧 Loss of power
🔧 Slow turbo spool-up
🔧 Excessive exhaust brake issues
🔧 Turbo barking or unusual noises
🔧 Check engine light
🔧 Codes related to turbo position or actuator performance

Many owners assume the entire turbo needs replacement, but that’s not always the case. Proper diagnosis is critical before spending thousands of dollars on parts.

If your 6.7 Cummins isn’t performing like it should, let us take a look before a small issue turns into a bigger repair.

💡 DIESEL TIP OF THE WEEK 💡

One of the most expensive mistakes diesel owners make is waiting until something breaks before performing maintenance.

A few simple services can prevent major repair bills:

✔️ Replace fuel filters on schedule
✔️ Service transmission fluid regularly
✔️ Keep cooling systems maintained
✔️ Check batteries before winter and summer extremes
✔️ Address small leaks before they become big repairs

Modern diesel trucks rely on high-pressure fuel systems that can cost thousands of dollars to repair if contaminated fuel or neglected maintenance causes a failure.

Preventive maintenance is almost always cheaper than corrective repairs.

Need help putting together a maintenance plan for your truck? We can help.

Diesel Tip of the Week 🔧

One of the biggest mistakes I see is replacing parts before properly diagnosing the problem.

Modern diesel trucks are packed with sensors, modules, emissions systems, and high-pressure fuel systems. A check engine light doesn’t always mean the part listed in the code is actually bad.

Accurate diagnostics can save a lot of time, money, and frustration.

If your truck isn’t running like it should, let’s diagnose it correctly the first time.

2019 expedition came in with smoke coming from the drivers side under the hood. We inspected and found a crack in the valve cover causing a nasty oil leak. Brand new valve covers on both sides and this customer was back on the road with no more leaks or smoking!
