What is a head gasket?

The head gasket is responsible for sealing pressure within a car’s engine as well as the distribution of oil and engine coolant.

Every time you turn on your engine the head gasket has to operate within very high temperatures and pressures, which is exactly what it is designed to do. The engine of your car needs to be cooled constantly as it relies on combustion for power and the head gasket is the core component in performing this job.

Why is damage to a head gasket a major problem?

If the head gasket is damaged, the engine will quickly overheat and serious damage will be caused. Overheating in the engine of your car will lead to a loss of compression, the mixing of oil, water, coolant as well as a reduction in lubrication.

The head gasket is a very complex piece of equipment and so a variety of materials are needed to build it. It has to be able to function normally at extreme temperatures and pressure. It also needs to be resistant to all of the chemicals and oils which rush around your car engine.

As a result, gaskets differ from one car to the next as the demands of each engine are unique. Car manufacturers like Ford, Vauxhall and BMW spend millions of pounds every year in the research and development of head gaskets to help manage the pressure and cooling of engines.
