Default 2015 1.4 head gasket?

Hey guys, having some issues.
Car is misfiring, coolant in oil. How many areas on this car can the coolant mix with the oil other than the head gasket?
Engine oil cooler? anything with the turbo? Intake manifold gasket? I am not familiar with these 1.4t engines.

Likely the oil cooler or the head gasket, or both. You have to get the antifreeze out of your motor oil as it with destroy your crank and
camshaft bearings. As a stop-gap you could run plain water without the pressure cap tightened down, which should slow down the coolant
leak into you motor oil until repairs can be done, .

The car has 22k miles... I'm not going to be driving it or anything. Just wanted to see other places to look at before I pull the head off.
