What Can Cause A Blown Mind Gasket Inside A Vehicle

The symptoms of a blown head gasket embrace potential alleviation and a Rugged sounding engine.

The tendency gasket seals the engine block to the cylinder sense in a machine. The belief gasket helps to assure compression. It extremely prevents coolant or engine oil from leaking into the cylinders. A blown head gasket can author distinct problems, ranging from compression loss to increased engine wear. Multiple parts of the vehicle are affected when a imagination gasket blows, creation it an indispensable Element. There are many reasons that a sense gasket may blow.

Compression Stress

The stress of compression in the cylinder can beginning a failure in the head gasket.Pre-ignition and pinging are major causes of head gasket failure. If the engine's fuel mixture and spark timing are off, this will cause excessive compression. This, in turn, increases the stress applied to the gasket, often resulting in leakage.


If the gasket continues to leak, it will cause severe damage to the vehicle. Newer head gaskets feature non-stick coatings that help to reduce stress on the head gasket.


The modern engine uses aluminum cylinder heads on cast iron blocks. Aluminum is lighter but expands faster than cast iron. The difference in expansion creates friction on the gasket. The gasket simply begins to leak.

Defective cooling fans or systems often cause the engine to overheat. If the radiator, thermostat, water pump, cooling fan or other cooling systems fail, the overheated engine can experience thermal expansion that basically crushes the head gasket. The seal is then lost.

Improper Installation

Often, gasket failures are caused by improper installation of the head bolts. All head bolts must be in good condition, cleaned and properly lubricated. Torque specifications must be followed to ensure a proper seal. Other installation errors include improper surface finishes, using abrasives to clean a head or block and the addition of a sealer to a coated composition head gasket.
