Oil Spotting below head on TC

Noticed slight oil spotting on the head/block interface...it's not coolant.

Behind fuel pump area:

Farther back on the rear side.. from above:

Any thoughts? It's not flowing..just spotting. Car has 20K mi.

I don't think there is any seal in that area? It's not the valve cover area.
Doesn't look like much of anything.

I just had my dealer fix that leak under warranty and when I got it back they did a shitty job of cleaning up oil that ran down to the bottom of the motor. I had to use 2 cans of brake clean to clean it up. At least the leak is fixed. Oh and they test drove it for 44 miles too.
