BMW Exhaust manifold gasket replacement

Do I Need to Replace My BMW Exhaust Manifold Gasket?

If your BMW has an internal combustion engine it creates an explosion inside the cylinder, this energy force is part of the engines cycle and in turn, creates the torque required to move the driveshaft which drives the wheels.

As part of this combustion process, the engine expels exhaust gasses. These gasses have to pass through the exhaust manifold, catalytic converter, resonator and muffler before they exit the rear of the BMW. They also flow past one or more oxygen sensors on the way through.

When the BMW engine expels the leftover gasses from the combustion process they are hot and the exhaust fumes can be dangerous as they can contain carbon dioxide (CO2), carbon monoxide (CO) and carcinogens.

BMW exhaust manifold gaskets are used to seal the connection between the cylinder head and exhaust manifold to stop any gasses from leaking out and melting things around the engine. An engine also likes to have a little back pressure, exhaust systems are designed to work with the engine so an exhaust leak can change how the exhaust leaves the engine.

BMW exhaust manifold gaskets can wear and fail over time or become damaged. When this happens you may notice increased engine noise, engine performance may be lacking, fuel efficiency declines, the check engine light might come on or you may notice a burning smell around the engine.

When your BMW exhaust manifold gasket needs to be replaced, it’s good to know AutoGuru.
