i have the same problem with my car, if its not mixing with the engine oil, your cylinder head has no crack yet. The cylinder head gasket is worned out or depleted which causes the engine to overheat. Better have your car be top overhauled and replace the cylinder head gasket and stop using it to minimize the cost of repair.
