Here are the effects of a leaking valve cover: 1. When the valve cover leaks, it can cause the vehicle to lose power or fail to start. 2. If the air-fuel mixture is too rich or too lean, incomplete combustion in the combustion chamber can lead to increased fuel consumption. 3. It can also result in slower vehicle speed, difficulty in starting the engine, reduced power, incomplete combustion, severe carbon buildup, and even cause individual cylinders to stop working. Here are the functions of the engine valve cover: 1. The valve cover is mainly connected to the engine's cylinder head. The camshaft is installed below the valve cover, and it seals some intake mechanism components on the cylinder head. 2. It ensures the normal operation and lubrication of the engine's valve drive mechanism, provides dustproof sealing, and forms an enclosed unit with other parts of the engine, ensuring a good working environment for the internal components of the engine.
