    Gasket, cylinder head

    The Gasket, cylinder head (4.20780) seals combustion, oil, and coolant passages between head and block. Replacing it with Porza quality restores compression and prevents engine damage.

    FAQ

    A gasket for a cylinder head, commonly known as a head gasket, is a sealing component placed between the engine block and the cylinder head. Its function is to create a tight seal that maintains compression within the combustion chamber while preventing the mixing or leakage of engine oil, coolant, and combustion gases.

    Key specifications include dimensions, thickness, material type (such as multi-layer steel or composite), and compatibility with the engine. The gasket must withstand high pressure, thermal expansion, and temperatures often exceeding +200°C, while maintaining a reliable seal under extreme conditions.

    Replacement is necessary when the gasket fails or is damaged. Common symptoms include engine overheating, loss of coolant, white exhaust smoke, oil contamination, or reduced engine performance. It must also be replaced whenever the cylinder head is removed.

    Porza offers a fit guarantee option where your vehicle or engine details are checked against product specifications. This ensures the gasket matches the correct dimensions, thickness, and requirements for your engine.

    Porza supplies high-quality sealing and engine components with fast delivery across Europe. Customers can order online or choose in-store pickup in the Netherlands, Germany, or Belgium. This ensures quick access to essential replacement parts for both professional workshops and individual users.

    If you select the fit guarantee, Porza verifies compatibility before shipment. If the product does not fit or meet expectations, it can be returned according to the return policy. This ensures a reliable and risk-free purchasing experience.
