Defects of the intake manifold gasket, their causes and signs

1. Warping. It occurs as a result of temperature changes, for example, in case of ingress of cold water on the surface of the extremely heated manifold. This leads to depressurization of the connection, signs of which are: lowering of the engine power, specific sound from under the hood, unstable operation of the engine at idle speed, increasing of fuel consumption.
2. Tear. Its causes are: low quality of the component, increased vibrations of the engine or errors during installation. According to localization, apart of the signs noted above, it may be manifested as stains of oil or cooling liquid in the intake manifold area.
3. Deformation. It may be caused by distortion of the cylinder head or the surface of the intake manifold. Sometimes it occurs in case of usage of poor-quality or too aggressive agents for components fixation, and also due to the influence of extremely high temperature, for example, when the manifold overheats.
