Plz nelp me identify what is this disconnected line - white smoke -

[shevin]

I was fixing vaccum leak and I replaced the hose that returns oil from bottom of CCV to next to oil deep stick. And i fixed the leak but now i get a white smoke smell like unburnt oil

I also noticed there is an un attached hose (its a bit stiff) that goes all the way down to the left of the oil bottom (not attached to oil deep stick bottom)

Here is the video
