What happens when an exhaust manifold gasket fails?
If the gasket fails and leaks near any plastic components, or engine wiring, the heat from the exhaust gases may cause the components to burn up. This may result in a burning smell coming from the engine bay as a result of the components being exposed to such high heat. The smell may sometimes be accompanied by faint smoke.
What causes a burning smell from the exhaust manifold?
