The exhaust manifold gasket is responsible to assist seal the exhaust manifold which contains post-combustion gases. Also preventing any leaks that happens in the exhaust system, acting sort of as a collector.
Exhaust manifold gasket functionThe exhaust manifold is setup to be a collector of the engine's gases that it releases. The engine is constantly pumping exhaust gases at high temperatures which exit through the cylinder head, and travel to the exhaust manifold. As pressure builds up in the manifold, the iron gasket enlarges with the cylinder head, manifold, and pressure forms without any gas leaving.
Various vehicles have the exhaust manifold which can be made from iron or can just be a set of pipes which both get the job done. Due to the fact that they are located in an area where the temperature is high, leaks are bound to happen.
Issues with a faulty exhaust manifold gasketA faulty exhaust manifold gasket can lead to leaks, a decrease in power, and poor fuel efficiency.
