Here's a strange update.
The next day I checked the van, no oil leak. I runs fine. I get a small dollar coin size drip after a 30 minute drive sometimes but not all the time. The oil level is now staying level at the halfway point on the dipstick. The oil that I sprayed of the engine ad auto transmission has stayed gone since I washed it so I assume whatever happened has stopped and its back to it old self.
I did stop by a place called ECS Auto a high performance shop with crazy custom racing stuff and told them what was going and they recommended to try a GUNK product
Gunk M1616 Bearin' Seal Engine Sealer - 12 fl. oz (http://www.amazon.com/dp/B000ABCHKU?tag=at56m-20) with a fresh oil change and to follow the instructions.
Of course they also said if it's serious its no substitute for fixing the seal and they also said if it's just a drop why bother?
