Oil/coolant intermix can be caused by a number of things. If you suspect the oil cooler, it’s most likely the 4 o-rings that seal it to the block. Not hard to replace the rings and you can test the integrity of the cooler when you have it out. To verify that the oil is indeed coming from the tube, you might clean it and then wrap a paper towel on the end. And, as Birddog mentioned, peer into the coolant tank.
The other obvious possibility in that area is the bottom line of the AOS is not well sealed.
