Good morning,

This sounds like you have a failed head gasket from the overheating.

You need to have a leak-down test done on each cylinder to confirm a failed gasket. That is where they inject air into each cylinder and check for coolant movement in the radiator. That will confirm a head gasket failure.

I attached the procedure for you of replacing the head gasket.

Let me know if you have any other questions.
