2005 f350 6.0 autotrans. 8000km on rebuilt motor. New updated stand pipes and dummy plugs. All new sensors, icp,ipr,ebp. Was driving and all of the sudden died, was running fine before hand. No weird noises just or bucking just like you turned the key off. Had it towed to ford. Suspect a massive high pressure oil leak or lpop failure. Funny thing is cranking afterwards was showing 0 icp, which i thought was unlikely to happen, and that was also the only code besides crank position sensor, i assume from cranking. I never checked the low oil pressure before it was towed. As far as i know 0 icp kind of rules out stand pipes, probly and ipr. In my mind only things it could be is lpop failure, stc fitting on hpop, im unsure if it was updated or not. Or possibly lpop pressure relief valve. Coud it possibly be a wire to the ipr or something to show a reading of 0 icp during cranking and no start.

Low pressure oil was always good before the incident, and high pressure oil also was really good before hand, no long starts or anything weird.

With 0 ICP, I would start with base engine oil checks and go from there, but I would have THOUGHT that Ford would have done the same...

Ford hasnt looked at it yet, happened yesterday, saturday. Hopefully hear something these week. My first thought was a low pressure oil issue, with a 0 icp thow.

This is what I believe also, but there have been a few cases where it SEEMS that a failed IPR might have caused 0 ICP. Even though there are one (maybe two) threads on it, I am still very skeptical. IMO, there are several factors at play in those cases (ie not just the IPR).

The main exception is when the ball blows out of the early HPOP, but even though that is on the high pressure pump, it is on the suction (low pressure) side.

Even if i had the non updated stc fitting still and it failed, i should still be seeing some icp pressure i would of thought, but maybe not if it completely come apart?

Good point - a catastrophically failed STC fitting could not get oil into the high pressure oil lines (ie no ICP pressure).

Anything that might COMPLETELY block the oil flow to the high pressure system, or cause it to completely drain out of the high pressure oil system while the LPOP is pumping, would cause 0 ICP.

Let's hope the ending isn't the same as the other guy on FTE...

Oh...not much - he just found a needle bearing from a failed lifter in his LPO regulator. So, he went from "my truck died in the store parking lot" to "I need a new short block..."

Ol, ya well hopefully thats not my case. Although my motor is still under warranty. You should know before hand a bad lifter thow wouldnt ya? Popping out intake or something, my truck sounded pretty good after the build.

Well, one who pays attention to things could probably pick up on a lifter headed south, but you'd be surprised. A lot of folks on here wouldn't bat an eye at a truck running on 7 cylinders either

Wait - It's a 6.0, so 6 cylinders, right?

No dude 6 is how many spark plugs it takes, like duh 🤪

Just heard back from tech. They claim its showing 20psi icp. Low pressure side was good. They were 3hrs into it to get that far. Now they claim another 3hrs to get to the hpop to check stc fitting. Ipr was good they tried another known good one. Im hoping its the stand pipes dummy plugs cause that would be under warranty, but when they did the build i chose to reuse my hpop cause it had very low km, im unsure if they put the updated sct fitting on it or used the non updated one so hopefully not that cause it wouldnt be under warranty. Could stand pipes and dummy plugs cause that massive of i leak, i dont think so but. Seems like alot of hrs to diagnose, but i know the hpop side leaks can be tricky.

I wish you were closer. We could save you a lot of time and money...

3hrs to tell you your LPO is good...I'm in the wrong business!

Haha, ya dont take much to pull the oil filter. They must of air tested the hpop system to in those 3 hrs. He said next step was to pull turbo and access hpop, which would be another 3hrs. Last time i pulled my turbo took me 20 min, and im just a simple rancher, no ford tech haha.

So supposedly, number 7 injector come apart on at oil rail at oring and caused a high pressure oil leak? That was only making 20psi? Didnt know such a high pressure oil leak was possible from an injector. Half the snap ring is missing they believe its in the oil pan, wasnt in the head they are going to search for it, and remove pan. All covered under warranty of that single injectors failure. These are motocraft injectors with like 8000km on them. Dunno what happened, installed by ford improperly, or just fauly injector.

Im notsure what this snap ring part from the injector is or how this injector come apart to cause such a hpo leak, he said they found all the parts of the upper injector except half of a snap ring type peice of metal, about thickness of fingernail, about 1/4 inch long.

I think its that snap ring intop of injector, above the oring, where oil rail connects
