Does a blown head gasket mean the motor is bad?
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.

What causes a blown head gasket ( BHG )?
A Blown Head Gasket (BHG) is where the gasket fails, and stops sealing. There are many reasons for this, and many effects of it failing. In simple terms the gasket breaks down, and allows the combustion gases to leak through into the cooling system and/or the lubrication channels.
How can you tell if your car has a blown head gasket?
The most usual means of detecting a BHG is by noticing your temperature gauge skyrocketing. A BHG does not directly cause the engine to run hotter – the break in the gasket allows combustion gasses to leak into the cooling system, forcing radiator water out into the overflow bottle.
