P0016—The Deadliest Code Your 6.7L Power Stroke Can Throw

It’s the fault code no Ford owner wants to see—the P0016 Camshaft/Crankshaft position correlation code. Unfortunately, once the P0016 shows up it’s usually too late for your 6.7L Power Stroke. S&S Diesel Motorsport’s Luke Langellier recently called attention to the ’11-present Ford V-8’s most devastating DTC (check out the video here). First off, with a press-fit crank gear, Ford only anticipated its 6.7L Power Stroke would see stock rpm, stock horsepower, and stock torque levels. Added horsepower—even in tune-only applications—brings added cylinder pressure with it, which increases the load on the cam gear exponentially. Beyond that, the CP4.2’s tendency to lock up during failure adds a tremendous amount of load to the geartrain—and that load carries downward into the cam gear as well as the crank gear. The result can be catastrophic: a slipped crank gear, incorrect valve timing, and piston-to-valve contact. Solution: use a reputable tuner and (if or when possible) weld the crank gear to the crankshaft.

Winter Projects

Billet Sigma, Meet Billet-Steel Block

Things are looking good for O-Line, the Super Stock diesel truck that debuted on behalf of WP Developments and Indianapolis Colt, Dalton Tucker, in 2025. Over the winter, and in preparation for two hooks in Florida this March, the second-gen is receiving a billet engine, a beefier front axle, and an upgraded water-to-air intercooler. For the ultimate foundation, a billet-steel block was sourced from Chaos Fabrication, along with the masterfully machined front cover you see here. The front cover will accommodate another masterpiece: a Sigma pump from Fair Valley Performance. The Sigma sports 18mm plungers and is capable of flowing an incredible of 2,350 cc’s of fuel. It’ll be matched with three 107mm Stainless Diesel turbos.

Operation 5-second Daily

Neal Nissen is trading in 6.70-second timeslips for 5.90s, and his Cummins-swapped half-ton Ram is currently under the knife at CC Elite Fabrication & Specialty Welding in order to make it happen. Among what amounts to a laundry list of upgrades being performed on his 2WD 1500, he’s making the switch from compounds to a single, 88mm Garrett GT5533R and roll cage updates are being performed to make the truck legal for 8.50s in the quarter. Extensive suspension work, including a reworking of the rear four-link is also on the docket, as is the switch from a panhard bar to wishbone to eliminate side to side rear axle movement. Last but not least, and in the spirit of building a true street truck, Neal’s Ram will retain its ice-cold A/C.

Trapped In Time

A True Gem—Listed For A Reasonable Price

$35K for a 35,000-mile VP44 Cummins? Well, at least it’s not the $70,000+ figures we’ve seen over the past several years. This one’s listed on Low Miles No Miles and it’s a well-preserved 2001 Laramie trim Dodge Ram 2500 dwelling in Fort St. John, BC, Canada. Just 57,743 kilometers (converted to 35,000 miles in the ad) sit on the odometer, and the 24-valve 5.9L ISB Cummins is backed by the NV5600 six-speed—making it an 245 hp/505 lb-ft H.O. model. A DSP fifth-wheel hitch and a spray-in bedliner say it’s ready for hard work—but the lack of wear and tear present on the 25-year-old Ram suggests it’s never been used for any type of heavy hauling. Without question, this second-gen has led a pampered, garage-kept life so far.

Emissions

DOJ: No More Criminal Prosecutions For Deletes

Last week, news broke that the Department Of Justice would no longer be pursuing criminal charges under the EPA’s Clean Air Act based on allegations of tampering with onboard diagnostic devices in motor vehicles. It’s yet another step in the current administration’s rollback of targeting small business owners (and even individual truck owners) for removing emissions equipment on diesel pickups. Kory Willis, owner of PPEI and one of the federal government’s biggest targets in recent years, celebrated the news—but was also quick to point out that civil penalties can still be imposed on violators. In summation, it’s a positive step toward making late-model diesels reliable, clean, and efficient again—but we aren’t out of the woods just yet.
