Gasket

Gaskets are literally everywhere in your vehicle. Your vehicle is composed of thousands of parts, many of which are joined together. Sometimes the seal between these parts–between the cylinder head and the engine block for example, is crucial. In these cases, a gasket is used to help provide a proper seal. These gaskets can be made of paper, cork, rubber, or metal plates, and can often fail, requiring replacement to keep more expensive parts from failing.
