Evo 9 stock turbo whines

Hellooooo all
My Evo 9 GSR is almost stock, lately when the turbo spools and gets up to 1.2bar a high pitch whining noise would appear from the turbo, it keeps whining until I change gear or so

What is happening? Is my turbo about to go?

Check your intercooler piping and your BOV seals. I have heard some pretty wicked whines from bad seals. Hopefully its not the turbo.

x2. I had a nasty leak at a BOV that made some weird sounds. A boost leak found a small chunk of the gasket missing that you could not see from a visual inspection.
