You’ll find this critical seal between the engine block and the cylinder heads. It should be typically made of steel or copper, although some manufacturers use graphite and there are even asbestos gaskets in older cars.
The gasket helps ensure that the engine remains fully pressurised during the combustion process. Remember that the dynamic release of energy when fuel is ignited drives the pistons – so any drop in pressure means a drop in power. Oil and coolant are also supplied to the engine through the gasket, which means that problems with the part could lead to cross contamination between the two fluids – a problematic scenario for any engine.
