Hose to no where?

[amaraann]

Hello all,

Apologies if this is not in the right area. I'm new to the forum. I have this hose coming out of the top right of my engine and it doesn't connect anywhere. I'm hoping someone can tell me what it is and where it supposed to go. I've done some Googling, but I'm not very car savvy so I don't know what to Google to get better results.

Any guidance is very much appreciated!
