I have done a search on other posts for this and found some things that I checked that do not seem to be the culprit(such as the broken dipstick tube mentioned by others).

Problem is on driver side upper engine area(maybe toward front) maybe under/near fuel cooler. What I do know is side of head, exhaust manifold, side of block, and then running back to bellhousing area is black and dirty with oil leaking from somewhere.
I figured on doing egr delete soon and getting in there a little closer than just looking from top without removing anything allows visually.
Just wondering if anyone else has seen this and what it ended up being?
Heres what it looks like now-not good I know

check the turbo boot right in front of the fuel cooler.
