Weird noise

[grandagent]

I was involved in a minor collison yesterday that resulted in a medium sized dent in my fender. But when I drive the car I hear this high pitched noise that is in sink with the turbo spool. It sounds like a tea kettle. The car has a slight loss in boost and otherwise drives fine. Any ideas of what it could be?

possibly a cracked manifold

It isn't the manifold, it seems to be coming from right around the blow off valve and around the ic pipes.

could be that your bov is stuck open a little or a tiny crack/hole in the uicp do you have the stock smic?

It ended up being a cracked gasket in the bov, fixed it and it wrks fine. THanks for your help hyena
