Upon diving into the "BOV" thread I was unable to find a similar problem to mine.
I have a TurboXS RFL BOV on my 2004 STi, and I have noticed that at approx 3k RPM I get a metal on metal vibration/rattle type noise. This valve was installed by a local shop so I am unaware of what may or may not be the issue. Is there an adaptor kit or do I have the wrong model for the STi that is causing the fitament issue? It appears to be rubbing/making contact with the small metal black tubing that runs on the valve cover.
Any comments/suggestions would be appreciated!
