So a blown head gasket can cause engine malfunctioning.Įngine overheating may cause a head gasket to blow and it may lead to a lot of problems like leakage of oil, leading to chronic overheating and oil dilution. The second task which a head gasket achieves is the prevention of coolant or engine oil leakage in the combustion chambers and prevention of their mixing. Sealing ensures that the vaporized gas in the engine does not leak out. Thus, a head gasket performs the important task of completely sealing engine cylinder from one side, to achieve and maintain the necessary compression pressure. For combustion to occur inside a piston chamber, high compression pressure needs to be achieved, which is made possible by the sealing provided by the head gasket. The automobile’s motive force is provided by an internal combustion engine which constitutes its heart. Head Gasket FunctionĪ head gasket is a type of gasket or seal, that’s fitted between the piston cylinder head and the engine block, inside a car. Last but not the least slow wear and tear over the car’s lifetime can eventually take its toll and might also be one of the prime causative agents. Another reason might be improper installation of the gasket. So, a head gasket made of iron is preferred, as it has comparatively lower thermal expansion rate. If the gasket is manufactured from aluminum, then there is a higher chance of having a blown gasket, due to that metal’s high thermal expansion rate. It strains the valves and the head gasket that seals the combustion chambers.īesides these, there may be some inherent structural problems, caused due to the wrong choice of material for the head gasket. The second cause is abnormal combustion, leading to pre-ignition or detonation problems of an engine. Ergo, when the temperature of an engine heats beyond a point, its metal body expands and leads to blowing of the head gasket. The first reason, already mentioned is engine overheating. There are two important causes of a blown head gasket. Here is a compilation of symptoms that you should check out, if you suspect a blown gasket. Expert car mechanics do it and so can you, with cultivated observation faculties. An ability to foresee the imminent engine disaster in the making, through the identification of blown head gasket signs, can save money and time. High future predictability is profitable in stock markets and minimizes losses in car repairs. Prime Blown Head Gasket SymptomsĪ blown head gasket can bring on repairs to the tune of $1000 to $3000. Ergo, it is mightily helpful to know the signs indicating a failed gasket. A blown gasket can cause some serious damage, costing substantially in car repair. The head gasket plays a crucial role in the overall functioning of an internal combustion engine in cars.
Overheating, coolant-adulterated engine oil, loss of engine power and white sweet-smelling smoke from tailpipes are some of the prime indicators of a broken head gasket.
