There are several possibilities, but most common is that pressurized exhaust gas is vented into the coolant chamber around the engine. That causes the engine coolant to blow out through the vent and the engine will continuously overheat. Other possibilities are: coolant can blow into the crankcase, pressurized exhaust gas can blow between two adjacent cylinders, significantly reducing power and economy. Head gasket failure is almost always caused by engine overheating.

Sure it will start with a blown head gasket. But, if you continue to run this engine with a blown head gasket you will destroy the engine.
Loss of power and hard to start.
No it will not. The only thing that will fix a blown head gasket is to replace the gasket.
There are several possible indications of a blown head gasket: If the head gasket is blown between adjacent cylinders there will be poor or no compression in either cylinder. Poor compression in any cylinder can be caused by a blown head gasket. That condition can also be caused by a burned valve or piston. Coolant in the crank case can be caused by a blown head gasket. Compression in the coolant can be caused by a blown head gasket. An engine with a blown head gasket usually loses performance and runs poorly or not at all.
Yes, I blown head gasket will definitely effect the emissions.
No, a normal tune up cannot cause a blown head gasket. A blown head gasket normally is caused by an engine overheating or by a defect in the gasket or head. If it happened right after a tune-up that is just a coincidence.
No. You can have the head gasket replaced. This is unless you kept driving the car with a blown head gasket and have totally destroyed the engine.
It is not possible to repair the actual head gasket. Repair of a blown head gasket is to replace the gasket.
