First 6.4 breakdown

Hey all,
Long time reader first time poster as my trucks been pretty good to me until last night when I had to be towed home. It’s a 2009 F-250 XL w/116k miles on it. I fear I may have caused this, let me tell you what it did then what I did. Driving home from work in heavy traffic check engine light comes on, she loses all power real fast while blowing massive amounts of white smoke till it come to a stop and won’t go anymore, will idle but that’s it. Limped it off the road barley but now it’s blowing black smoke under the hood from what appears where the turbo bolts up to engine. It limps a few feet and engine dies, won’t accept any throttle, while idling barely any exhaust coming out the tail pipe and the dpf/cat area sound like an air compressor dumping 200psi while there’s still black sooty smoke coming from turbo area. Now here’s what I did, I started ordering all the delete parts for this truck. While waiting for the exhaust to get here I installed the H&S xrt pro and downloaded the dpf delete but left all oem parts intact, thinking only driving about 30 miles or so tops before doing the delete pipe and egr delete wouldn’t hurt but, I was dead wrong. Any idea of what’s going on, would be greatly appreciated. I’m hoping once all the parts get here and I replace the exhaust and egr shell fire right up, but afraid I damaged it pretty good and won’t be the case. Any help would be gratefully appreciated. Oh should mention this truck just recently moved from Alaska to Charleston SC where it went from long driving to congested city traffic.

just a guess, but you have a leak somewhere around the turbo(needs fixed)
and your DPF is plugged
can you disconnect the exhaust somewhere before all that? -- then see if it starts and runs better

In my defense, I was unsupervised

General note:
For all those wanting a premium silicone sealer Kubota 70000-73764 is the best your gonna find. This is a hybrid gray silicone that uses solvent rather than acid to start the curing reaction, this makes it safe for aluminum and and any surface that involves coolant.

Yeah. I’m hoping that’s all it is. New exhaust is supposed to be here on Tuesday. And I try that, guessing all the pressure that couldn’t get buy the dpf was blowing back up and escaping where it could, possible blown seal. I just hope there’s no major damage.

6.4 up pipe cracking is one of the most common failure points on the motor. Leaking around the firewall just behind the turbo is generally where they crack. The back pressure could/crack them. I would get a mirror and light and do some looking.
