If you’ve got oil pooling in the 7.3 engine valley (under the fuel bowl/HPOP area), the HPOP is always on the suspect list—especially the rear/end plug and the high-pressure discharge fittings. You ca

The 6.0L Powerstroke EGR cooler gets blamed for a lot, and sometimes it deserves it. White smoke, coolant loss, degas bottle puking, sweet exhaust smell, and repeat EGR codes can all point toward an E

The 7.3L Powerstroke is reliable, but it’s not magic. It still has 20-plus-year-old seals, sensors, wiring, filters, and plastic bits trying to survive heat, oil, fuel, vibration, and whoever owned th

The 6.0L Powerstroke EGR cooler has a bad reputation, but the cooler itself is not always where the problem starts. In a lot of cases, the real failure begins with a restricted engine oil cooler. Due

The 7.3L Powerstroke is simple, reliable, and painfully honest. If fuel supply is weak, dirty, restricted, aerated, or leaking, the truck will let you know. Fuel system upgrades are not just for big i

On a 7.3 Powerstroke, the oil cooler “assemblies” (aka headers or mounts) aren't just end caps—they're the oil filter base, and the in/out for oil and coolant into the cooler. It’s also home to key pi
