Head gasket functions:

• Combustion chamber seal: The main function of the head gasket is to provide a tight connection between the engine head and the engine block. This seal is necessary for the proper functioning of the combustion chamber, where the combustion of the fuel-air mixture takes place.
• System separation: The head gasket separates the oil, cooling and coolant systems from the combustion chamber. This prevents these fluids from mixing, which is crucial for proper engine operation.
• Resistance to high temperatures and pressures: The gasket must be made of a material that is resistant to high temperatures and pressures generated during fuel combustion. This ensures its durability and reliability in extreme engine operating conditions.
• Surface Fit: The gasket is designed to perfectly fit the surface of the head and engine block, ensuring an effective seal and minimizing the risk of leaks.
