My turbo has been sounding like garbage lately with the siren noise that i'm sure means it's dunzo.
I decided to check out the engine bay for anything suspicious. This is what I found.
What is apparently a Vac-line coming from the turbo goes to a valve above the airbox.
This valve has disintegrated and whatever it's function the hole means it's probably not working anymore

I don't know if it's related to the impending doom of my turbo.
What do you guys think?
What the hell is this?

That vavle is part of the EVAP system, not turbo. You can get a replacement from ECS tuning for about 13 dollars.

Doubt that it is related to turbo noise.
