intake manifold whistle?

[Carmenpzito]

I smacked a curb pretty good the other day (front end bounced nice and hard) and now when i drive in vacuum or boost there are two whistle type sounds coming from the center dash/firewall/intake manifold area. Looking at my boost gauge the vac @ idle is normal (around 18-19inHg) and while cruising @ 3200 rpm its like 24-25inHg. I hit max boost just fine (12psi). I checked my IC pipes and TB for rips or damage but everything looks normal. All vac lines are secure too. Not really sure what else to check?

A boost leak test may reveal your problem.

It's actually deceiving where those sounds are coming from so you really need to do a boost leak test to know.

Could be loose nuts or a messed up gasket. When my jpip gasket was loose it whisteled when i reved my enging beacuse of the air blowing in between the gasket. Slounded like a dying cat.

Do a boost leak test, it will be the only way to determine where the leaking air is coming from.
