How Long Does a Cylinder Head Gasket Last?

[MaggieFitz]

Cylinder head gaskets typically have a service life of about two years. Types of Cylinder Head Gaskets: Metal-asbestos gaskets use asbestos as the base material, wrapped in copper or steel sheathing. Some have woven steel wire or perforated steel plates as reinforcement, while others feature metal rings around the cylinder holes to enhance strength. The advantage is their lower cost, but they have relatively poor strength. Due to the carcinogenic effects of asbestos on humans, developed countries have discontinued their use. Metal gaskets are made from a single piece of smooth steel plate, with elastic ridges at the sealing points that rely on the elasticity of the ridges and the effect of heat-resistant sealant for sealing. These are widely used abroad. The advantages are high strength and effective sealing, but the cost is higher. Features of Cylinder Head Gaskets: This sealing gasket has a composite structure, with embossed galvanized steel strips on both sides serving as the core plate. The surface is rolled with soft material, and the sealing gasket usually has a layer of anti-stick coating on the surface.
