Overheating then this

[ard]

^Agree.

The issue is coolant>>>>oil

Not oil into the coolant.

Just a random google quote:

It really depends on just how hot the engine actually got, especially the head itself, but it doesn't sound good. The basis of the problem is that the engine, like the great majority of modern engines, uses an iron block and an aluminum head. The head is where most of the heat is generated and the aluminum helps manage that. Anyway, aluminum expands right at twice as much as iron does when heated, which forces the head to bow up (warp) between the head bolts. That in turn exposes the soft part of the head gasket to combustion gases and destroys the head gasket, and all that can happen within about a minute.
