Major Oil Leak

99 F250 2WD 7.3L Has serious oil leak. Valley of engine filling and overflowing down back. Have replaced HPOP, New Fittings and Orings. The oil leak worsened this weekend and the truck died, 9qts low on oil! Refilled oil and it started after roughly 30 seconds of cranking. Drove to my shop and shut truck off. 10 Minutes later went to start truck to pull into shop, took about ten seconds of cranking to finally start then idled rough for about 20 seconds. Seems like the pressure is leaking off when I turn the truck off. Ive got some UV die and am going to see if I can locate the exact point of the leak. Im just really confused as to why this oil leak will not stop. Am I missing something?

One thing my mechanic and I did to diagnose where the leak was coming from was to THOROUGHLY degrease the entire engine bay. Get a couple bottles of Purple Power and start spraying that thing down. Repeat the process like 3 or 4 times. Cover the entire engine bay with degreaser, hose it off (all when the motor is cold).

Then once it's clean enough you could eat off it, run the truck with that UV dye, and you'll see only the freshest leaks.

Have you replaced the high pressure oil line (breaded) o-rings going into top of valve cover? Also o-rings under turbo and turbo pedestal. Sounds more like a blown high pressure line with the amount of oil you are leaking.
