宝马Z3Intake Manifold Gaskets Replacement at your home or office.

When to consider replacing the intake manifold gasket:

内部或外部泄漏。由于持续的温度膨胀和发动机零件的收缩或过热，垫圈的密封能力可能会毁坏，从而导致诸如：以下问题：

• 内部或外部发动机冷却液泄漏。In some applications, the manifold has cooling passages within. If the manifold seal to the engine fails, coolant can leak externally or even into the engine oil crankcase, where coolant can be noticed in the engine oil.
• 引擎过热。如果歧管处的泄漏是发动机冷却液的泄漏，则可能导致发动机过热。但是，还有其他导致发动机过热的原因，因此机械师必须确定实际原因。
• External oil leaks.在大约6和8个气缸发动机上，进气歧管位于发动机块的油润滑区域。如果歧管垫圈发生故障，则油会从发动机的外部泄漏到发动机的外部。
• 发动机操作不佳，精益操作，闲置。由于有缺陷的垫圈会破坏空气燃料比率，真空气体泄漏到了歧管中。发动机可能运转良好。
• Check engine light.Minor leaks at the intake manifold gasket will not usually cause the check engine light to illuminate. However, as a leak persists, it may grow larger and it possible for the leak to degrade engine performance enough that it will cause a trouble code to set, which will cause the check engine light to illuminate.
