Could he just put on a lower oil cooler like my S4 has and plug the ports on his radiator?

I went through this whole saga. hand wringing, thinking it could be the head gasket. This opinion and than on the forums but also helpful information. I replaced the radiator with an incredible aluminum one from 928 Motorsports, it is a work of art and solved the problem.

The way I would do it is to take the radiator out. Disconnect the oil lines. Fill the radiator with water. Pressurize the oil cooler and wait to see bubbles inside the radiator.

Drain the system, remove the reservoir and clean it in the sink to get rid of the sludge and residue, before putting it back.
Then fill the a bucket with warm water and dissolve a lot of detergent in it, fill the car and top off with more water before running the car until its nice and warm, then drain ( from the radiator *and* the block drain plugs) - I did two cycles of this to make sure it was clean.
Flush thoroughly with water afterwards until the lemon scent has gone

Dishwasher detergent is good for cleaning all the oily crap out of the system - its non-foaming (this is important! don't use clothes washer detergent), and breaks down the oil very effectively.

The reservoir looks like a PITA to get at. How much did you need to remove to get it out?
