What happens when a gasket blows?
A blown head gasket can cause engine malfunction and significant loss of engine power [source: Bumbeck]. Check the engine coolant level. If the car is constantly losing coolant, it may be because your car’s coolant is leaking from the cooling system into the oil pan. This happens when the head gasket is blown.
Can a head gasket blown without overheating?

What does a bad gasket sound like?
If the head gasket fails in such a way it allows the compressed air/fuel to escape, the compression of that cylinder is reduced. This loss of compression results in a rough running engine and a notable reduction in engine power. This sort of failure typically is accompanied by a sound like an exhaust leak.
