Massive 4.8L Oil Leak - See Picture - Help Needed

[juthale]

My 4.8L dumped 4 liters of oil in less than 5 miles yesterday. Bless my wife's heart, she obeyed the computer and stopped driving immediately when the critically low oil warning appeared. The car is back home over the pit, and now I'm trying to sort out exactly what the source of this leak is.

When the engine is running, oil comes in a steady stream from between the engine and the front differential (driver's side of the engine). From below, looking up between the differential and the engine, the leak is higher up than I am able to see - above the highest visible mounting bolt for the dif (see photo). I am unable to see the area of the leak from the front of the engine. I've removed the inner fender, but can't see it from the wheel well. I've removed the intake and the air dam and just about every other reasonably easily removed part, but I can't see it from above. There seems to be no easy way to get eyes on the leak.



Two questions for the experts:

1. Any thoughts on what might be the source of such a prolific leak in this area?

2. Any ideas on the easiest way to get in for a better view of what's above the differential?

I'm a licensed mechanic, so I'm not worried about doing whatever is needed, but I'd really love to avoid any more unnecessary disassembly as I try to sort out what the problem is.

Thanks in advance!
