Default What is that?

Hi there,

Since a little while, I hear a vacuum/sucking sound only when I turn the vents off and the sound stays until I turn off the car. I think it comes from behind the intake manifold. Today I was replacing the oil pressure switch behind the manifold and I found that the two hoses connected to a single hose (circuled in blue on the picture) behind the manifold were kinda melt down and disconnect.

Is anybody here could tell me what are those hoses??

Thanks!

Those are for the PCV system which connect to the pcv valve.
