I feel like this is a really silly question but here goes.. Since having done the repairs on my car and replacing the UICP, intercooler itself, and filter I've notice my blowoff valve sound changes from time to time. I've checked all the connections and made sure everything was tight, felt around the intake tube (short of removing it) to check for cracks/tears/holes/leaks, tugged around on the couplers and clamps, thought maybe the recirc tube was damaged but no.. boost builds perfectly fine through and through, car runs and idles just fine. Just concerning that a set unadjustable BoV can change noise as if it were being adjusted.
The noise it usually a nice short high pitched whistle which is seemingly more noticeable with the cone filter, but of late has been changing randomly to more of a less restricted sound if that makes sense. Like as if it were vented or set too loose, it tends to sound more like someone blowing through a straw. I can try and make videos but that depends on what it currently sounds like.
I first noticed it on Friday last week during it's first long ride, about an hour or two in changed from the norm. This morning on my way to work was like that for the entirety of the 20 minutes drive when it had been sitting all night. I had read on checking the turbo which when I fitted the Injen intake felt fine but I did not use any pliers to move it, just by hand. I could not feel any play either in and out or side to side. Any thoughts would be appreciated, thanks.
