Appreciation post: My uncle's weird trick for a 6.0 Powerstroke actually worked
My uncle, who's been wrenching on semis since the 80s, told me last month to stop chasing the usual suspects on a 2005 F-350 with a hard start. He said, 'Forget the FICM for a second and check the dummy plugs on the high pressure oil rails.' I thought he was nuts because the truck had good oil pressure, but I was desperate. Pulled the valve covers in my shop in Boise, and sure enough, the o-rings on both dummy plugs were shredded to bits. They looked like black confetti. Replaced them with the updated kit, and it fired right up like a new engine. I'd have wasted a whole weekend and a grand on a FICM for no reason. Has anyone else had a 6.0 problem that turned out to be something simple everyone overlooks?

Life's full of those moments where you spend hours chasing the COMPLEX thing when the simple fix was right there.

Man that's a killer story. Had the exact same thing happen on my 04 F-250 last year, except my "uncle" was a guy named Dale at a truck stop in Wyoming who told me to check the standpipes before anything else. Those little o-rings were so dried out they crumbled when I touched em. Whole job took like 3 hours and saved me from chasing a ghost for days. Its wild how the high pressure oil system on these trucks just makes people think its the end of the world when its usually some stupid seal.
