Recently, whenever I am in boost, I get a high pitched EEEEEEEEEE sound. It runs fine, but its supper annoying. Hopefully the videos work. https://plus.google.com/photos/1174...s/6041503627289681297?authkey=COWvm6WYpZ613gE Any ideas on what it could be?
I had the same thing with an old bov it had major leaks so all in all mine was a boost leak at high boost
+1 for doing smoke or pressure test for boost leak. there are many DIY instructions for making a contraption to test this on the cheap and easy
Ever found the problem I'm having issues with it as well got a new bpv and still got that high pitch noise?

I had this issue on my old wrx. Sounds like a ballon when you pinch the end correct? Check the gaskets on the intercooler. The bov gasket and the ones on the back for the y pipe. Make sure the bolts are snug.
Surlyoldmanmn- that's a very solid point I'll check that out today Mnrex07- yep that's what it sounds like annoying but that's the case Thanks a bunch
It was a silicone hose from the tb to the tmic. It was too long. Once I trimmed it down a little the squeaking went away. Essentially a boost leak, but I could not detect it with my boost leak tester.
That's right where those couplers usually live. If it's silicone it's aftermarket. Wonder if you just had a janky fit. Usually I hear about issues with those being too short if anything. Probably fixed it just be putting it back together snug... Regardless, success!
Finally found out the problem it was what u suggested surlyoldmanmn the throttle body to the manifold ohh well won't be needing to worry about it anymore getting it replaced soon
