Cylinder head gaskets are a particular type of gasket. Sealing pressure increases at the combustion chamber, which, to- gether with the combustion chamber bead, accomplishes gas sealing. Its main job is to seal against combustion pressure on the cylinder so oil and coolant can properly flow between the block and head without leaking into the combustion chamber or mixing with each other. Any leaks between them will cause engine failure; or significant problems like burning oil. Beginnerâs Guide: what is a throttle body and what does it do? Inside an engine you have a piston going up and down within a cylinder.Â, On top of the cylinder you have the cylinder head, which allows the fuel/air mixture to enter, and the exhaust gases to leave via inlet and exhaust valves.Â, Without a good seal between the cylinder head and the cylinder, when the piston rises on the compression stroke some of the air/fuel mixture will be able to escape, resulting in a loss of compression.Â, In order to form a good seal around the top of the cylinder, the head gasket features steel rings, known as fire rings.

Nowadays, MLS (multiple layered steel) or copper gaskets are more popular. It also needs to do the same with the waterways, so that coolant can also circulate freely around the engine.Â, But what makes a head gasket different from any other gasket is that it also needs to seal the cylinder to prevent the engine losing compression. Modern vehicles are commonly manufactured with an engine block and a cylinder head bolted on top, which makes a head gasket a critical seal. Historically, graphite and asbestos was a common composite material. A busted head gasket that is ignored may require repair of the engine block, cylinder heads, or a complete engine replacement. Without the gasket the seal between them, the two components would fail, causing a loss of pressure that would in turn reduce the power output of the engine.
