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?

Honestly, I've seen way more blown FICMs than bad dummy plugs (though that's a solid find). Those engines are just a box of surprises.

Ugh, tell me about it.
