7.3 idi troubles.
I'm staring to really hate my idi. I can't find the oil leak anywhere on the motor. There's so much oil on the back side of the motor you can't see it. Its got a really bad leak and all I can think of is to pull the moter out and look it over better. I have to add 1 quart every week cause it dripping out so bad. I don't want to drive it any more with the way it is. But it's a fun truck to drive.

Sounds like over pressurized crankcase and rear-main seal. Or it could be a leak oil pressure sender. Its on the very back of the block center/left.
Take it to a "you-wash" and pressure wash the hell out of it.
Where is the highest point of oily? IE just above starter, only above oil cooler, transmission completely black?

I have a after market oil pressure gage and when I put it in I sealed the threads. It shows 40 psi at 2000 rpms. Its not leaking from the oil cooler. I have a road draft tube. But I have had it a few months and the truck just started leaking about 4 weeks ago. It is oily all over the back right side, right springs, starter, oil pan, and transmission.
