Can i drive my car with a cracked Head?

Eventually the car will not drive. You can also end up doing more and more damage. If the oil and antifreeze is mixing then you may have to flush your entire cooling system. An oil change is a definite. Also, the antifreeze can be diluting the oil thus more damage to the bearings and other components. Best option……change the head

Heads seldom cracks, most problems are caused by a bad head gasket due to overheating.

Continued driving would get you stranded sooner or later and instead of head repairs, you might need a new engine by then.
