Oil pressure is everything for a 7.3L. One of the most common questions we get asked is related to how to test the High Pressure Oil Pump (HPOP) on a 7.3L Powerstroke. We say related to, because the h

If your OBS 7.3 (’94.5–’97) has random misses, contribution codes, rough cold starts, or the classic “it runs better when I wiggle the valve cover plug”… you’re not imagining it. The under-valve-cover

The 7.3L Powerstroke engine uses a HEUI (Hydraulically Actuated Electronically Controlled Unit Injector) fuel injection system. This means that the fuel injectors are actually fired by highly pressuri

Some 1994.5–1997 OBS 7.3 Powerstroke trucks used an early-style EOT sensor that is now obsolete. If your truck still has that old Engine Oil Temperature sensor and it fails, the correct repair is to u

Riffraff is a term for the common people, or hoi polloi. The term is derived from Old French “rif et raf” meaning "one and all, every bit."

When building or modifying a 6.0L Powerstroke diesel (2004.5–2006 Ford Super Duty), reliability upgrades often focus on major systems like head gaskets, the oil cooler, and EGR components. However, on

Looking to upgrade the headlights in your 1999-2004 Super Duty? The headlights found on 2005-2007 Super Duty's are a great option. Not only do they look better than their predecessor (1999-2004), they

The 6.0L Powerstroke is not the engine you diagnose with hopes, guesses, and a Facebook comment that starts with “my buddy’s did that.” A good scan tool is mandatory. Not just for codes, but for live

The Exhaust Backpressure Valve on the 7.3L Powerstroke is a common leak point. So common that most of us just simply remove it altogether. Why it's there in the first place: The EBPV was originally i

There’s dozens of recalls associated with our trucks. Some of these we’re all aware of, some are news to us, and some (the mass majority) truck owners were never even told about. It’s an interesting l

If you’re done trusting (and fighting) the aging factory 4x4 hubs (or anything with plastic where it shouldn’t be), the WARN Premium Hub Set (38826) is the industry-standard fix: all-metal constructio

The Cam Position Sensor (CPS) on all 7.3L Powerstrokes can be its Achilles heel. This sensor tells the PCM where exactly the rotating mass is in its journey. Without it, or with one that isn’t working

The 7.3L Powerstroke doesn’t have too many sensors compared to more modern era diesel’s, but the ones it does have all play important roles. This week, we’ll be diving into the Exhaust Back Pressure S

If you’re hunting a replacement front wheel bearing/hub assembly for a 1999–2004 Ford F-250/F-350 4WD, the first thing that matters is stud thread pitch. This Axiom unit is specifically for coarse thr

The 5R110 TorqShift used behind the 6.0L and 6.4L Power Stroke is a strong transmission, but just like anything else, it's not bullet proof and will need repair from time to time. Fluid, electrical, h

Our Patented Injector Cup/Sleeve Tool Set for the Ford 7.3L Powerstroke Diesel is the result of 12 years of refinement by 7.3L enthusiasts. 12 years of testing and tweaking until it was absolutely per

Just like our 7.3 recall list, on this 6.0L recall list, we’ll concentrate on drivetrain related recalls and include links to documents where we can find them. Some recalls listed on the NHTSA site ha

Lifter failure is one of the 6.0L Powerstroke problems we'd rather catch early, before it completely destroys the engine. The 6.0 uses hydraulic roller lifters between the camshaft and pushrods. Norma

A 6.0L Powerstroke with P0299 underboost or P0234 overboost is telling you the turbo system is not matching what the PCM commanded. That does not automatically mean the turbo is bad. Before replacing
