How serious is an exhaust manifold leak?

An exhaust manifold leak can allow toxic engine exhaust into the cabin of your vehicle and also reduce your vehicle’s efficiency. A leaking manifold is also dangerous for your engine over a longer period of time, as it can cause a burned exhaust valve, leading to a loss of engine compression and power.

Can you drive with an exhaust manifold leak?

Driving with an exhaust leak is potentially dangerous as the fumes contain carbon monoxide. An exhaust leak can decrease fuel efficiency, causing your engine to work harder, and you to fill up your gas tank more frequently. A third sign your exhaust may be leaking is if your gas pedal vibrates while you are driving.

What happens if you don’t fix an exhaust manifold leak?

What happens if you don’t fix an exhaust manifold leak?
