GrayZee Posted June 4, 2004 Share Posted June 4, 2004 Ok, if the PCV valve is at the bottom of the intake what is that thing on the top under the throttle rail? It's connected to the tree of hoses that lead to the AAC, air switch and Jpipe. I'm gonna start taking unesessary stuff off but I don't know what the that thing is.. Looks like a extra PCV valve to me, can someone explain it's pupose please? Quote Link to comment Share on other sites More sharing options...
Guest De Schmaydee Posted June 5, 2004 Share Posted June 5, 2004 Vacuum Control Valve....i think its there to minimize the effect of the throttleplate slamming shut under boost.... ....s Quote Link to comment Share on other sites More sharing options...
