The main function of a head gasket is to hold engine compression while keeping oil and coolant circulation separate. Undetected blown head gaskets cause coolant and oil mixing, which could lead to severe engine damage, such as engine block cracking.
Answer A cracked head means the head itself has a crack in it. Usually between the valves. A blown head gasket means that the gasket that sits between the cylinder head & the engine block has a crach in it allowing the oil and water to mix.sually, when a head gasket goes bad, it is caused by a warped head. Heads warp when the engine overheats. In an extreme case, when an engine overheats the head and/or engine block can crack. But in any case, all are caused by an overheated engine.
