The Exhaust Manifold Gasket in your INFINITI is a multi-layered gasket that creates an airtight seal at the connection point formed by the engine and exhaust system. Whenever the Exhaust Manifold Gasket is operating as it should, it serves to keep sufficient pressure in your vehicle's exhaust system so that exhaust gases are pulled away from the engine and surrounding systems.

If you start to hear hissing, sputtering, or tapping sounds under the hood (and if you notice them right after starting the engine), an old or cracked Exhaust Manifold Gasket might be the culprit. A damaged Exhaust Manifold Gasket could cause engine gases to become stuck in the engine bay under the hood. If the issue isn't remedied quickly, those harmful gases could reduce the engine's performance and fuel efficiency. Engine byproducts and exhaust gases are very hot, which means that a leak in your Exhaust Manifold Gasket could also lead to burns and warping on nearby parts in your vehicle's engine bay. If that's happening in your INFINITI, you will probably detect a burning plastic smell, and you might even see smoke coming from under the hood.

Your INFINITI can't get you anywhere without a properly working engine, so an old or damaged Exhaust Manifold Gasket is one repair you should look into fixing as soon as possible. When it comes to a replacement Exhaust Manifold Gasket, turn to INFINITI Genuine Parts.
