I'm new to this forum but it looks like it's full of very knowledgeable people. I hope to receive some of your help in addressing a problem I have.
I have a 08 wrx with AVO intake, AVO TMIC and a catback exhaust. Every other engine/powertrain component is stock.
It looks like I lost my boost. I don't have a turbo pressure gauge so I can't quantify this problem. However, when I punch the gas around 3k RPM the turbo spools (I think, unless its just air going through the air intake) and then I hear a high pitched farting noise - just like when you spread apart the opening on a balloon full of air or blow through a blade of grass. It sounds like it's coming from the left side of the engine bay (when in the driver's seat). Could it be that the BOV has been damaged due to boost creep (is that even possible with my setup)?
I checked the hoses around the turbo and intake and didn't find anything wrong...the brass pellet is not missing either.
I still have to double check the connection leaving the TIMC but I don't have easy access to those connections.
Also, when I let off on the throttle I don't hear the BOV go off like it used to...but that's probably because the pressure isn't there in the first place.
Can someone offer some advice before I start removing parts?
Also, do you think my warranty will cover this (if I leave the intake and TIMC on)? What if I put the stock intake and TIMC on?
Any help is appreciated.
