Default Coolant and oil mixed

Our 2012 CX9 starting making a squealing noise like a belt was loose. Took it to our mechanic, the oil dip stick looks like a peanut butter milkshake. Up to this point, we hadn't had any problems. Change the oil every 5k miles. at 100,000 miles had a tune up and check up on it. we only have 144k. Has anyone else had an issue like this. Literally no issues then the engine just crapped out.

If you're lucky it's just the oil cooler. If not then it might be a head gasket.
