You can pull the adapter without dropping the oil, but you will lose some, make sure you have an extra quart to top it back off.

Finished! I hope this guide helped you fix your leak!
I just took mine off and cleaned it put new gaskets then pilled the lines off and plugged it those damn lines kept leaking no problems since.
What would be the harm in this ? I bought a 97 recently and the radiator is leaking, oil cooler lines have evidence of a leak, and the cooler adapter housing is leaking. I'm considering getting a radiator with no cooler and plugging the holes in the adapter housing. I have a Duramax to pull/work with; this is just a ride around truck- no towing at all. If so, what is the thread on the fittings at the adapter ?
