Engine oil in radiator 2005 WK 5.7 Hemi

I have just discoverred that there is a lot of engine oil mixed with the coolant in my radiator. So much that the dipstick barely registers any oil in the sump.
Is the oil cooler part of the radiator and can it be tested for leaking and if it is part of the radiator can it be repaired or will I have to buy a new radiator?

It could be blown head gaskets.

There is only a transmission oil cooler in the radiator. Could indeed be a problem with a head gasket, eventhough normally the coolant goes into the oil. When you run the engine, do you see any air bubbles showing up in the coolant recovery tank? (try to increase the rpm as well when you look).
I don't know the 5.7 to be able to tell you where else oil and coolant could mix.

Head gasket is a good bet. Aside from oil being in the coolant, have you taken off the oil filler cap and looked to see if the wall of the filler tube is coated with a milky looking substance....coolant in the oil. Very unusual problem, unless someone has been messing with the engine and/or it's been badly overheated.
