You might check the oil cooler on the top of the engine for leaks -- either in the oil cooler or in the o-rings.

___ SORRY READ CLOSER ____ you already changed this to no avail...

Since you are getting oil into your coolant and not the other way around -- that's not as severe.
On my old S Coolant in the oil prompted me to do a complete rebuild 10 years ago. (failed WP lead to a freeze plug failure in the head).

I think there is also a path for the oil to enter coolant via the AOS - but I'm not 100% sure there.

Otherwise its either cracked cylinder head or cracked cylinder liner.
