The valve cover in your Lexus ES300 serves as a protective covering of the valvetrain, which holds the rocker arms, valve springs, push rods, lifters, and cam. It constantly receives its lubrication every time that the engine is running. Oil is pumped up through the pushrods and is dispersed underneath the valve cover to keep the rocker arms and other parts lubricated. In order to maintain its proper lubrication and to prevent the oil from leaking out, the Lexus ES300 Felpro valve cover gasket set must be employed. This is the complete set of sealing devices that will provide a firm and leak-free bond between the valve cover’s mating surface. It includes the left and the right valve cover gaskets and the 6 spark plug tube seals. These are made to be thermally and chemically resistant to the by-products of the engine’s combustion process. The valve cover is often the source of leaks in the engine that is why it is a must to gear it with a tough valve cover gasket for best performance.
