What is an exhaust manifold gasket?
An exhaust manifold gasket is a gasket that lies between the engine block and exhaust manifold at the point where they connect. It is designed and tested to withstand the incredibly high temperature of the engine block and to contain the strong pressure of emissions pushing their way through the motor and out to the manifold. The manifold gasket is typically attached to both surfaces with gasket sealer and then secured by the bolts that hold the manifold to the block. What can go wrong with an exhaust manifold gasket? Worn down by the heat and pressure that occurs in the motor and through to the manifold, the gasket can begin to wear down and allow leaks or spaces to form. The manifold gaskets are made of composite material that will usually hold up well to the demands of the engine, but on occasion, they can start to leak or tear. Other exhaust manifold problems occur as a result of human intervention. Examples would include a bad car accident, the gasket being improperly replaced aft
