Have the cooling system flushed and add either G-12 or universal yellow antifreeze.
If G-12 was mixed with green antifreeze, it gets like mud.

For the oil cooler, I don't know how the internals work. However, it sounds like they want to replace the turbo and oil cooler because those are the 2 most likely places that the oil and coolant can mix together.
Replacing the oil cooler appears to be ver simple compared to replacing a turbo. There's the oil filter, one nut, the cooler, and an "o" ring gasket/seal.
13. O-ring
14. oil cooler
15. oil filter
16. nut

Well the thing is it looks like mud. There's def something more than antifreeze in there. The reservoir is clear and you're supposed to be able to check the level just by looking straight through the plastic, but it's so muddy in there you can see the level at all.

Thanks for the diagram - that's perfect. Is that from a chiltons? No pictures. the car is at the shop now and I believe they flushed and cleaned it all. I'm trying to decide whether to have it towed home and try to work myself on it or just have them start by replacing the oil cooler.
So oil and coolant CAN mix in the turbo? Some people above say it can't.

defienatly the oil cooler because it happened to me.
Because of ther higher oil pressure to the coolant the solder joint inside seeps the oil through.
When you remove it cover the in/out for the water and blow into the oil pipe closing one end . You should feel the air getting through and that will prove it.

id say it most likely the oil cooler, the coolant and oil go through a little box together that passes themnext to eachother with fins on all sides...
you can get them from ecs tuning...
a head gasket could also be the problem, but the oil cooler is often the verdict in this kind of problem.
your turbo might be bad just because of lack of lubrication from the oil with coolant in it...
i'd say replace the oil cooler and flush your coolant system, and do an oil change then see where you are... no sence in doing $3000 of work while 300 would do the trick, if it still persists, then i would move on to a new turbo (ko4 ahem...) and replace the head gasket..
my money is on the oil cooler 100%

If no G12 around use water.
