Is an exhaust manifold leak dangerous?
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.
What causes an exhaust manifold to leak at the end?
Inspect all sides of the exhaust manifold. The donut gasket, found at the end of the exhaust manifold between the manifold and the downpipe, can also leak.
