Your INFINITI's Engine Exhaust Manifold Gasket is a multi-layered gasket that seals the connection formed by the engine and exhaust system. Whenever the Exhaust Manifold Gasket is functioning perfectly, it serves to keep sufficient pressure in your vehicle's exhaust system so that exhaust gases are drawn out of the hood compartment and away from the engine and surrounding systems.

If you start to hear sputtering, tapping, or high-pitched hissing noises under the hood (and if you notice them right after starting the engine), an old or cracked Exhaust Manifold Gasket might be at fault. A leaky INFINITI Exhaust Manifold Gasket can cause engine gases to become stuck in the engine bay underneath the hood. If the issue isn't remedied quickly, those combustion byproduct gases could diminish your engine's performance and fuel efficiency. Exhaust gases can reach extreme temperatures, which means that a leaky Exhaust Manifold Gasket may lead to significant burns and warped parts on nearby engine components. If that's happening in your INFINITI, you will probably experience a strong odor of burnt plastic, and you might even see smoke coming from under the hood.

Your INFINITI wouldn't go far with a compromised engine, so a leaking Exhaust Manifold Gasket is one repair you'll want to make immediately.
