Default 1988 f250 oil leak!!

ok so i have a 1988 f250 with a 7.3l ats turbo and a whole bunch of other stuff, well she has been parked for over a year, and the last couple days i have fiddled with getting her started, upon start up i have a couple leaks from the return lines(o-rings on the injectors) kinda expected that, but i have oil filling up in the valley pan and running out the drain, and i cant figure out where it would be coming from, of course i cant see it either, so i am looking for advice, its not from the turbo feed line or the return, but it is DUMPING oil, i lost about 1.5gallons in 3 min......HELP!!!!

i don't know if this will help but my dipstick came out once and it was spilling out so much oil it looked like I had blown one of my main seals you could check that.

nope, after the first start up and leak checking, i restarted the motor, and visiably watched the oil fil up the valley pan, and start down the drain, from under the truck it was coming from above the starter, i traced it back up to the valley, but i dont know what could be leaking into the valley....tomorrow i will pull off the set the motor to tdc, and pull the injector pump and intake, and look at the whole scenerio, it may be the valley pan itself isnt sealed all the way...damn i was hoping to do some scrap metal runs this week!!! i dunno what else to do

ya they are great, i think it is the oil return for my turbo, it has a drain tube that goes into the lil hole in the valley pan that has an rubber plug, i think the rubber plug has either worked itself loose and isnt sealing around the return tube, or it isnt located right in the valley pan, and is causing the leak, i am finally getting to tear into it tomorrow

FYI, you can NOT get that grommet anymore. ford or ATS dont sell it. ATS quit making parts for our motors, so in my mind they can suck a big fat donkey shlong. i took the ATS crap off my truck and sold it before i had any issues. for now it can stay NA.

so i tried to goop it up after i coudnt find another grommet, and that didnt work, it is still leaking, any ideas, would be greatly appreciated!!! i have welder buddy that has relocated his t88 turbo to the area where the a/c compressor is and he has his return in the oil fill cap, seems like a great idea... but i would still have to plug the hole, does anyone know if hypermax makes it?
