Oil leaks - Mystery

[Pimpin Dsmstyle]

More info. If the car is cool, you start it, run it for awhile... it will not leak. You almost have to get it up to operating temp before it will even start to leak. I'm about >< this far from pulling off the front case. We have ok oil pressure until it gets warm, then it goes down the shitter. It starts off solid ( for a used engine) at the bottom line that shows it's ok, but after running it for about 5 minutes, the pressure starts to drop towards the 20% range. I really have no idea what could cause this.

The oil APPEARS to be coming from the crankshaft pulley and/or the oil pump gear area. We all know how oil works and how it can be decieving so if anyone has any last minute info, please let me know
