The side effects of a blown head gasket include oil and coolant mixing, poor performance, and smoking. This is a serious issue which can quickly lead to catastrophic engine failure. The side effects of a blown head gasket include oil and coolant mixing, poor performance, and smoking.
The head gasket is the thin piece of gasket material that is between the engine block and the head. The head gasket fills small imperfections in the head and creates an air-tight seal between the two surfaces, note that it is a seal that is capable of enduring tremendous extremes of heat and pressure.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.
