- In addition to improving engine efficiency, a high-quality front valve cover gasket can also enhance engine performance. A properly sealed gasket ensures that the engine runs smoothly, with minimal noise and vibration. This can provide a more enjoyable driving experience and may even increase the resale value of the vehicle.
× - The function of the head gasket is twofold. Primarily, it seals the combustion chambers, ensuring that the high-pressure and high-temperature gases produced during the combustion process remain contained, driving the pistons and thus propelling the vehicle forward. Secondly, it seals the water passages, preventing coolant from leaking into the cylinders or the oil galleries, which could lead to engine failure.
