I believe I have a boost leak on my evo 8. My Bov is recirculated from the inter cooler piping to the intake piping. one side is connected to the inter cooler piping and the other is to the intake piping. I'm missing that piece on the left side beside the bov as shown in the picture below the silver piece with ridges. Is that causing my boost leak? Its running 50/50 but is that piece required or no?
