UPDATE: I got a chance to get up underneath the car after I degreased it down. Took a couple of pictures. The first set is with the car running on ramps until the cooling fans kicked on. The second group of pictures is from a 15 mile drive to and from the parts store. Seems to look like the oil pan gasket is leaking, I changed this in 08' when I bought the car.... I did notice after the trip I got it back up on ramps and witnessed a drop of oil from my oil pan gasket to my filter. Sorry for the shaky pictures Maybe time for a new oil pan gasket?
First set of pictures dry, on ramps, running to get the fans to come on.
These are pictures after the drive.
See what you can find when you've got a CLEAN slate to start with. Like I said earlier, it's amazing how far and how many places hot oil on a hot surface can spread. Especially with highway speeds adding to the equation.

Very true, Thanks Bing. I'm going to start degreasing it more often lol.

Lol that will be my next option if this don't fix it , But I'm no metallurgy expert but wouldn't it be hard to overtighten the bolts without the bolts snapping first,( I had this happen to me when I was 16 and didn't know the difference between in/lbs and ft/lbs at the time and was torqueing down a bad pan gasket and snapped the bolts... pan was fine, but I had to tap and thread the block fun times down memory lane lol ) and the pan gasket has a type of "stoppers" built in by Fel-Pro to prevent this from happing IIRC.
Take a straight-edge and make sure the flanges are flat. If they aren't, pound them flat with a block of wood and a hammer.
Bye Bye: RIP sandrock

It does look like the gasket is squeezed out in one pic.
