Exhaust Manifold Gasket.

• Creates a seal between the engine and exhaust system
• Helps maintain pressure in your exhaust system
• Replace when worn out or leaking

Your INFINITI's Engine Exhaust Manifold Gasket is a gasket assembly that creates an airtight seal at the connection point where the engine meets the exhaust system. Whenever the Exhaust Manifold Gasket is working as it should, it maintains pressure in your vehicle's exhaust system so any combustion byproducts and fumes can be pulled away from your engine (and away from the cabin air intake).

If you hear tapping, sputtering, or noticeable hissing sounds coming from your engine (particularly right when you start up your vehicle), a damaged Exhaust Manifold Gasket may be at fault. A damaged Exhaust Manifold Gasket can lead to exhaust gases becoming trapped in the space underneath the hood. In turn, these gases could affect your engine and weaken its performance and fuel efficiency. Exhaust gases are extremely hot, meaning that a leaky Exhaust Manifold Gasket could also lead to burns that can melt or warp nearby engine components. In those cases, you'll likely experience a strong odor of burnt plastic, and you might see smoke seeping out from the sides of your hood, as well.

Your INFINITI can't get you anywhere without a properly working engine, so a leaking Exhaust Manifold Gasket is an issue you should look into fixing as soon as possible.
