Hello everyone,
i have a Mini Cooper 2010 who had the engine overheated,I replaced the water pump and the pipe coolant.
i also removed the thermostat housing and it was melted,the valve cover also need to be changed.
since I didn’t performed a pressure test I don’t know if the head gasket and pistions rings are ok ?
what are the chances that I will need to remove the cylinder head and replace other parts ?
thank you.

Heck for coolant in oil; chocolate looking oil. Or oil in coolant. If no signs of either do a compression test.

Thank you for your response
I changed the thermostat housing but I can’t start the car it’s goes freak you can the see that on the video below
