Automobile engines are almost like self-contained machineries that smoothly operate with the help of lubricants. To prevent overheating of moving parts due to friction, lubricants must be prevented from being spilled from the engine system. Lubricants allow moving parts to slide smoothly with minimal resistance. When there is no enough lubricants, the moving parts such as the valves will slow down and begin to heat up. The heat will cause the moving parts to expand or become deformed. Consequently, when this happens the moving parts will cease to function. On the other hand, even though the lubricant may be sufficient, the moving parts may still malfunction because of contaminants. Contaminants such as moisture, rust, dust and debris cab increase the abrasive action of the moving parts. Valves are particularly susceptible to solid contaminants. The contaminants can lead to clogging and deterioration of the moving parts. Energy will be wasted in counteracting the resistance caused by contaminants. To prevent lubricants from being spilled or contaminated, valve cover gaskets such as the Mazda valve cover gasket are integrated with valve covers.
Valve cover gaskets such as the Mazda valve cover gasket seals the valve covers with the valve trains, preventing lubricants from being spilled. Lubricants circulate the engine parts as long as the engine is running. The reasons behind this operation are both mechanical and logical. In mechanical terms, the oil lubricant circulates the engine block because of the oil pump. The oil pump drives the oil to circulate. However, the oil pump is powered by the camshaft. N turn, the camshaft is powered by the crankshaft, which is ultimately connected and driven by the pistons. Consequently, when the engine is not running, the oil pump will also be unable to function. Hence, the oil lubricant will be unable to circulate. On the other hand, logically speaking, there would be no need for the oil lubricant to circulate the engine block when the engine is not running because there would be no moving parts that require lubrication. Lubricants are only needed by moving parts to minimize friction and heat. Moving parts such as valves only need lubricants when they are operational.
When the engine is running, the lubricants automatically circulate the engine block. However, if the valve cover gasket or other gaskets are not tightly sealed, the lubricants will be spilled. Typically, the lubricants must be allowed to be collected in the oil pan. This will not be possible if the engine is a leaking contraption. Some amount of lubricants will evaporate while some amount will leak, drenching other parts that do not require lubrication. A valve cover gasket such as the . A valve cover gasket is typically constructed out of metal, ceramic or composite material such as carbon fiber. Since the engine produces extreme thermal energy, ordinary rubber or plastic cannot be used because these gaskets will only melt. Valve cover gaskets are highly resistant to heat. These gaskets do not easily expand or contract even when under extreme temperature. Consequently, the gasket will not easily be loosened. The oil lubricant will not be spilled from the valve train of the engine.
