What causes coolant to leak from a blown head gasket?
Overheating as a result of a blown head gasket Possibly the most common head gasket leak symptom is engine overheating. When a head gasket malfunctions and fails between the cooling system and the combustion chambers, it can result in coolant leaks and engine friction.
What are the symptoms of a leaking head gasket?
Some coon symptoms of head gasket failure are engine misfiring or leaking between cylinders. Evidence of engine misfiring can be seen as lowered compression, rough idling, engine overheating, coolant leakage, and coolant leaking on top of the spark plug.

First of all, an internal leak can be worse than an external leak.
What happens when your head gasket goes out?
If the head gasket fails in such a way it allows the compressed air/fuel to escape, the compression of that cylinder is reduced.
