What causes a blown cylinder?

1. Overheating: When an engine overheats, the metal expands and pinches the head gasket so it no longer seals properly. Pre-Ignition Problems: If the timing of the combustion process is off even slightly, it can send too much pressure into the cylinder head. This can cause the head gasket to fail.

What does it sound like when your head gasket blown?
