Symptoms of a Bad Intake Manifold Gasket
With repeated exposure to heat cycles, dirt and debris and lack of cooling system maintenance, the intake manifold gasket can become brittle and crack, leading to gasket failure. Symptoms of a failing intake manifold gasket include:
Coolant internal leaks may also cause:
- Rough running/engine misfire
- White smoke from the tailpipe
- Coolant loss resulting in engine overheating
- Coolant loss into the engine oiling system may result in contaminating engine oil
- Green, red, yellow, or blue leaks under vehicle
- A sweet smell from under the hood with no visible signs of leakage on the ground

Why Do Intake Manifold Gaskets Fail?
Heat and age are the enemies of the intake manifold gasket. If the engine overheats, the extra heat can stress the gaskets, over-compressing them and the gasket material may not recover to provide adequate sealing. Additionally, like many parts on your vehicle, the normal wear and tear of daily driving can cause the intake manifold gasket to fail. In some cases, the engine castings may be made of different materials that have different expansion rates which scrub the gaskets. At the automotive repair shop, technicians use a smoke machine to test for intake manifold gasket leaks at the intake manifold runner areas. A check engine light with lean engine codes and/or engine misfire codes are other signs of a failed intake gasket.
