Owning a 6.7-liter Power Stroke V8-equipped Ford F-Series Super Duty pickup brings immense capability, but also specific known issues that could lead to huge expenses. Catching these vulnerabilities early saved money and kept your truck reliable. Justin from JH Diesel and 4×4 shared shop insights in a video. He covered common problems seen on these trucks and recommended preventive steps.

Justin, a working shop owner, offered his perspective on the 6.7-liter Ford engine. He called it “a really really really good engine” But, he pointed out, “They do have their issues though,” and in his video, he detailed these problems and discussed the fixes he recommended.

One key concern Justin highlighted was the crankcase filter (CCV). Neglecting its service could build pressure that pushed oil out of seals, particularly the upper oil pan. Justin told his audience that this can become a very expensive problem in the long run.

That’s why working on the whole oil pan was a must. “I recommend to people that if you do this, it could save thousands and thousands of dollars on repairs,” he pointed out. Another weak point was the CP4 (Common Rail high-pressure pump) high-pressure fuel pump. Justin explained this pump was prone to failing.

The severe outcome happens when: “When that factory CP4 pump goes bad it internally grenaded 90 percent of the time.” Metal can spread throughout the system and force a costly full replacement.

Plastic fuel filters presented danger, too. The top filter’s fitting could break and spray fuel onto the hot engine. “It’s been common and notorious for these things to catch on fire and burn to the ground,” he said since plastic under-filters have their risks like getting damaged from road debris.

To address these points, Justin recommended preventive upgrades that he called “bulletproof.” “This right here, I would say, is probably about the bulletproof package if you own a 6.7 Power Stroke,” he stated.

It included an updated OEM CCV filter, an SNS Motorsports DCR pump (which replacing the CP4 high-pressure fuel pump), and billet filter kits from Fleece Performance.

Justin summed up the result if these fixes were not done: “because these things could … one leave you stranded on the side of the road … two cost you thousands of dollars, and three … they could possibly burn the whole truck down.” He credited the companies and gave them shoutouts as well.
