What are the symptoms of a bad intake manifold?

What is a single plane intake manifold?
- A dual-plane intake manifold has two separate plenums that each feed only four cylinders, while a single-plane intake manifold has a single, open plenum that feeds all eight cylinders.
What is dual plane intake?
- A dual-plane intake actually separates the manifold’s plenum into two sections. With a dual-plane intake, each plenum and four intake runners are connected to every other cylinder in relationship to the engine’s firing order. Because of this, each side of the manifold is only subjected to pulses from every other cylinder in the firing order.

Another symptom of a potential problem with the exhaust manifold gasket is a burning smell from the engine bay. 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.
