Cylinder Head Gaskets
Cylinder head gaskets are a particular type of gasket, they are designed to sit between the cylinder head and engine block. They are used in all types of internal combustion engines, but most commonly in road vehicles such as cars and trucks.
Like any type of gasket, the purpose of a cylinder head gasket is to seal the gap between two surfaces (in this case the cylinder head and the engine block). This, therefore, ensures there is no leakage of either liquids or gases into or out of the join (in this case the leakage of exhaust fumes out of the exhaust system).
No Leaking Fumes
The consequences of leakage in exhaust systems can be catastrophic. Firstly, there’s the environmental impact of untreated exhaust fumes leaking into the atmosphere before being passed through a catalytic converter. But also, the potential for fumes to leak into the passenger cabin can be fatal, with carbon monoxide poisoning being a real possibility. It is for this reason that well-made cylinder head gaskets are absolutely vital in any internal combustion engine.
Cylinder Head Gaskets – History
Over the years, cylinder head gaskets have been made from a number of different materials. Historically, composite materials, for example, graphite or asbestos were used. However, these were phased out due to environmental and health concerns over asbestos. As well, due to the fact that the materials were far more prone to head gasket blow-outs than more modern materials.
Nowadays, MLS (multiple layered steel) or copper gaskets are most commonly used. Copper gaskets allow the cylinder to bite into the gasket, improving the seal and the life of the gasket itself.
Gaskets are not expensive to buy. However, the cost of replacing a blown gasket and potentially repairing the engine block following a blowout can be extreme. Therefore, regular maintenance and checks are highly recommended.
Having a head gasket blowout on any type of internal combustion engine can be catastrophic and very expensive to fix. Maintenance, however, is relatively inexpensive and can ensure ongoing safety.
