It means that the head gasket (which is the seal between the engine block and the head(s)) has failed. This often happens as the result of a rough running engine putting a lot of stress on the gasket, or simply from old age. This failure tends to present itself as a sudden and occasionally violent breaking of the afore mentioned seal thus giving it the term "blown".
Because the head gasket is blown.
what are you asking here? PLease be more specific ...like - how do I know if my head gasket is blown, or what do I do about a blown head gasket ......
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.
No it will not. The only thing that will fix a blown head gasket is to replace the gasket.
Yes, I blown head gasket will definitely effect the emissions.
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.
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.
