Coolant leak?

I just dropped this freshly rebuild motor into my truck a month ago. I've put about 2500 miles on the new engine. For the first 1500-1750 I was leak free. Now I seem to have a coolant leak. It looks like it is coming out where the oil cooler meets the block at the front of the motor. I rebuilt the cooler and the cooler itself doesn't seem to be leaking. I double checked the 2 bolts holding the cooler to the block and they are TIGHT...

Coolant only leaks when motor is warm and is off. Checked the Tstat housing and it is dry as a bone.
It doesn't look like a bad oil cooler o-ring but it's hard to see up in there.

Clean the area look from the top to see if any coolant is leaking above where you're seeing the leak. I'd also use a pressure tester as well and check in front of the leak incase the fan was blowing the leak backwards

Did some more investigating. The leak is in fact coming from where the oil cooler meets the block.

If I wipe off the oil cooler neck where the coolant is collecting (with engine off), coolant appears seconds later. I hope I didn't crack anything. Any tips on removing this bad boy?
When I rebuilt the oil cooler, it was out of the truck.

I believe I found my culprit. I pulled everything apart and made a huge mess. After I got everything cleaned off I couldn't find anything that may have caused my leak. Then I took a closer look at my gasket and found this!

That sucks are you planning on changing the oil after everything is back together?
