Mysterious Oil Leak

[Super_Dave]

Project BABA YAGA! got a 700r4 installed last Friday. When it came time to dial in the shift points, the truck would choke out badly. Crap in the gas tank was in the filter. While diagnosing the problem(s) I noticed the harness smoking with the key in the on position. Turned it to off and it stopped.

Towed the truck 3 miles to a friends shop. Went by today and noticed an oil puddle under the front of the truck. Looked underneath and it had drops all across the lip of the cross member. Got up and looked over the drivers fender and noticed the lip of the cross member was pooled in oil.

Keep in mind:
The truck has been sitting, locked for a week.
The truck has never leaked oil.
The engine was professionally built and has less that 600 miles on it.
The engine, while sitting, has lost 2/3-3/4 of a quart of oil.

I find it hard to believe the pan gasket went bad while sitting,
I find it hard to believe the front seal in a fresh 600 mile motor went bad while sitting,
I find it hard to believe all the things that are going wrong in the past three weeks...

Anyone have any ideas where such a spontaneous and aggressive oil leak would be coming from while sitting?
