Hi all can anyone tell me what this hose is? Have an annoying whistle when boosting hard so I thought I would check any hoses for holes. This black one is the only one I can see with a hole. Has melted.... Tia

That is the PCV (positive crankcase ventilation) hose.

Resurrecting a not so old post...
Did this cure the whistle noise?
I have a similar noise I was trying the solve, the symptoms seem the same.
