Basically, you heat the car up and draw air from the recovery tank. If the test fluid changes color, there is exhaust gases present in coolant. Normally, this would diagnose a blown head gasket, but I am pretty sure this isn't the issue.
next I want a compression test and leak-down.
Is there anything else besides a oil cooler failure (heard this is rare), o-ring failure (again, rare) that causes intermix besides the dreaded cracked head? I haven't heard too many happy stories with intermix, so...

Testing the space above the coolant for exhaust gases is a very common and reliable method to help determine the cause of the issue. If no exhaust gases are present, the intermix can be from something like the oil cooler; but if the gases are found, you have a crack somewhere in the combustion chamber area.
