Also like to add that have a street tune on the truck and was doing a 0 to 60 run when all this happened....im thinking the high fuel pressure blew something out but I'm just not sure how it led to dumping several quarts of all onto the street....

The fuel isn't high pressure until it's leaving the injector. As for the oil, there is a orb port for the high pressure oil at each cylinder in the head. That is where those hoses are run to. The rest with exception or #2 all have plugs with o-rings that can fail. #2 has the ICP sensor and another o-ring that can fail. Then the hoses have fittings with seals that can fail. At the hpop there is 5 or 6 ports/plugs and the IPR valve. On the low pressure side is the turbo and pedestal o-rings, and if you were pushing it when whatever let loose, pretty easy to lose a lot quick.

I don't know how much cranking was done after the failure or how much oil was went where, but if it's as much as you think then an air pressure test may be a first step. Cody Test is a common name for it, but air like water will find path of least resistance. So if there is an injector o-ring blown, which explains oil in bowl, the air will find the easy way out.

My prime suspect would be a blown HPOP line to a head. The engine will not run when it's that low on oil so that's why it won't start. If your HPOP lines are old, you can just replace them when you clean it up before filling the oil and starting again. They need to be replaced sooner or later anyway. Or you could just clean it up, refill oil, start it and see what you get. An oil leak like that won't be hard to find.

I apologize I thought I read the fuel filter had oil in it. If that's not the case then Walleye is right leaking hpop line very likely candidate.

So I inspected those oil lines to the head. I peeled away the wire protector on them and the passenger side one was covered with oil while the other wasn't. Pushed air through that line and oil comes pouring out the braided line where it is all frayed so found the leak..thanks all!!

@Homerunking2394 , if you are looking to replace the HPOP lines, there are several options available to you.
You can go with OEM hoses and fittings: https://www.riffraffdiesel.com/hpop-related-1/ or https://www.dieselorings.com/1999-20...-oil-pump.html
Aftermarket hoses and fittings: https://www.riffraffdiesel.com/hpop-...de-head-99-03/ or https://cncfab.us/
Homebrew which can be sourced at hydraulic shops around the country, just be sure to use the proper hose ratings and fittings.
Years ago I installed new HPOP fittings, new head fittings and upgraded Motorcraft lines. I did not care for the bare braided lines offered by CNC Fabrication and Riffraff did not have their JIC fittings/hoses out at the time. Recently I had a HPO leak at the passenger side head fitting, but a 1/3 turn tighter and it was good to go.
Good luck to you!
