Sandywhips Posted August 4, 2019 Share Posted August 4, 2019 I took of my intake manifold recently and found that it was wet and smell of gas. Also the channels were grimy and wet, along with one of the vacuum lines. What would cause gas to make it back into the plastic housing? Side note; The throttle body is still clean, and the gaskets are brand new. Quote Link to comment Share on other sites More sharing options...
