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.


Yes, I blown head gasket will definitely effect the emissions.


It can as one or more cylinders may have a misfire. A blown head gasket will destroy your engine.


It sounds like a blown head gasket to me. Take it to someone that has a exhaust gas measuring tool and they can tell you for sure if it is the head gasket.


Yes, that is possible. A blown head gasket will destroy the engine.




It is not wise to drive with a blown head gasket. If you continue driving with a blown gasket, eventually your car will over heat and the engine will seize up. This can cause accidents if it occurs while driving.



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.


No, only a blown head gasket or cracked head will cause coolant to mix with the oil. A leaking valve cover gasket will only cause oil to leak onto the engine block externally.


you have a blown head gasket water is getting in to the engine oil



It can if the cylinder fills with coolant.



The most common cause of a blown head gasket is an over heating engine. Low coolant or coolant not circulating through the engine causes the engine to heat up and the gasket to fail.


Overheating can cause this. Air bubbles escaping from the radiator is caused by a blown head gasket.


The main cause of a blown head gasket is engine overheating. Of course it can be a manufacturing defect but that is not common.


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.



A cracked head or a cracked block can also cause this.


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.
