A head gasket is a vital part of the engine, designed specifically for cylinders\u2019 protection and to prevent them from engine oil infiltration or coolant. It ensures optimum compression of the cylinders. Therefore, a blown head gasket can be damaging for the cylinders as well as for other engine parts<\/a>.\u00a0<\/p>\n\n\n\n

It is imperative to detect a head gasket leak early on to avoid expensive repairs. Let\u2019s discuss the probable causes of a blown head gasket,  signs of a bad head gasket and more. <\/p>\n\n\n\n

WHAT CAUSES A HEAD GASKET TO FAIL?<\/strong><\/h2>\n\n\n\n

The head gasket endures a lot of stress when the engine operates. The major causes of a blown head gasket are detailed as under:<\/p>\n\n\n\n

ENGINE VIBRATIONS<\/strong><\/h3>\n\n\n\n

Vibrations are normal for an engine as it operates. However, these vibrations can fatigue the head gasket over time. The gaskets are sandwiched between the engine block and the head via head bolts. With regular fatigue, the head bolts start to weaken, break or warp and allow increased friction and vibration to damage the gasket. If the design lacks sufficient clamping force from the head bolts, it can also eventually cause failure.<\/p>\n\n\n\n

MECHANICAL PRESSURE<\/strong><\/h3>\n\n\n\n

Every time the cylinders fire, the detonations in a vehicle\u2019s engine yields a significant level of pressure. By the passage of time, this type of pressure stresses head gaskets and may crack them up and cause leakage. <\/p>\n\n\n\n

OVERHEATING<\/strong><\/h3>\n\n\n\n

The vehicle must not overheat, or it will cause damage to the head gasket and other components. Moreover, the coolant must never run low, or else a lack thereof won\u2019t be able to pull engine heat from the block and heads. As a consequence, the extra heat causes expansion on the head gasket and conveniently blows it up. Therefore, you should keep a check on the causes of engine overheating <\/a>and take timely measures to prevent it.<\/p>\n\n\n\n

LIFESPAN<\/strong><\/h3>\n\n\n\n

Another factor is age. Like any other component, the head gaskets have a lifespan. Over the years, the seal can break down and cause leaking to occur. To avoid this, make sure replacements are carried out in due time as per the manufacturers prescription before you hit the mileage.<\/p>\n\n\n\n

IMPROPER INSTALLATION<\/strong><\/h3>\n\n\n\n

At times, the head gasket or the coolant system gets installed or repaired improperly. The leaks and problems with the engine temperature, therefore, become big issues as a consequence. <\/p>\n\n\n\n

THERMAL EXPANSION RATES<\/strong><\/h3>\n\n\n\n

Since its normal for engine to produce heat as it operates, the head gasket receives a high level of mechanical and thermal pressure, which gradually damages the gasket. This happens when the engine block and the head gasket has a significant difference in thermal expansion rates. <\/p>\n\n\n\n
