Liquid silicone manufacturers tell you that high performance engine cylinder head gaskets function like sealed O-rings
The engine manufacturer is concerned about the failure of the gasket, which is operating under sufficient normal load conditions. But as the compression ratio combustion pressure rises, the gasket may not be able to maintain a leak-free seal. Once the hot combustion gas starts blowing past the gasket to burn the armor, bad things start to happen. Burning armor cracks or burns through, compression is missing and gaskets fail. Or oil and coolant, start looking for new ways to run the engine inside, often with negative consequences.
For years, performance engine manufacturers have utilized various methods to keep the engine sealed with o-rings using wire in the combustion chamber and to run solid copper head gaskets. Silicon rubber sealing ring manufacturer to introduce all kinds of sealing solutions is also used in sealing gasket manufacturer after development of high-performance engine such as high temperature special coating graphite and non asbestos gasket, enhanced combustion armor, stainless steel or copper wire ring chamber internal armor reinforced head gasket, large wire ring and armor is the function of the combustion chamber is similar to the o-rings head gasket.
Multilayer steel (MLS) head gasket is one of the most popular products for high-performance engines in recent years. MLS gaskets first appeared on Japanese engines in the late 1980s and early 1990s, and were later adopted by Ford's 4.6L V8 series and Chrysler's 3.5L V6 and the new Neon. Gm also uses an MLS head gasket for LS1 / LS6 series engines.
