The material of head gasket
Various materials are used to produce head gasket, main part of
head gasket set, the first kind is MLS or Multiple Layers Steel –
Most modern head engines are produced with MLS gaskets. These
typically consist of three layers of steel. The contact faces are
usually coated with a rubber-like coating such as Viton that
adheres to the cylinder block and cylinder head while the thicker
center layer is left bare, the second kind is Solid copper – a
solid sheet of copper, and typically requires special machining
called 'o-ringing' that places a piece of wire around the
circumference of the cylinder to bite into the copper. When this is
performed copper gaskets are extremely durable. Recently companies
have started producing copper gaskets with integral sealing wires
permitting their retrofit into engines without the removal of the
engine block for machine work, the third kind is Composite – an
older technology. Typically these are made from asbestos or
graphite but are more prone to blowouts than newer gaskets.
Asbestos gaskets are becoming increasingly rare due to health
concerns, the fourth kind is Elastomeric – a gasket type used by
Rover on their K Series engines. It utilised a steel core plate
with molded in place silicone rubber beads to seal oil and coolant
passages. The bores were sealed by rolled steel fire rings in a
more conventional manner. The idea behind the gasket design was to
produce a production version of the technology used in F1 engines
at the time. The original application of the gasket on the smaller
versions of the K Series was very successful. However, an engine
redesign resulted in persistent problems with the design – the
joint interface became unstable and the gasket could not cope.
