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

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

Is that connected to anything or just free ended ?

I found this thread that might be related to me https://xoutpost.com/bmw-sav-forums/...tion-pipe.html

so I think that pipe needs to be open ended, but now I have to figure out what caused the White smoke, when I started the car when I put everythiing together I saw a LOT of smoke.

One thing could be because I did something stupid, I forgot to buy throttle body cleaner and I didn’t open the the throttle body, so I sprayed a bit of W40D and wiped it out with a cloth…


Today I opened the the thorttle body and I found some Oil in it,… but I dont think a bit of spray of W40D could have that much oil in there… I am thinking the Return Oil Pipe that installed for the CCV is not correctly installed and that’s why oil is coming back…


Right now I took out both TB and idle control valve and cleaned them with TB cleaner and Carb cleaner for IDC. I am praying that is gonna be fixing it.




Question when there is a lot of White smoke coming out of the car, after I start, is that dangour ? (I turn off the car immodestly because the Smell of it is REALLY strong and around whole car got white smoke…..but maybe I should drive it a bit with white smoke and maybe it will go out ? What do you guys thing?

Possibly....drive the car maybe 30 min that should burn it off!

one odd thing about my car when I used REALOEM to
Find “Crankcase Vent Pipe - Return Pipe from Connecting Hose”
It gave me this part number for my VIN: Part #: 11-61-7-504-536-M58

And I ordered it from pelican parts that has no wires around it, but my own original pipe had Wires in them…right now I disconnected the wires and they are Open. I have no idea why Return Oil Hose should have had WIRES in them… I know it is cold package my car but the wires dont seem do be used for heating or anything like that.
I wonder if this could be a source of problem, that my replacement part didn’t have a connector for wires and they are now all open


If you wonder whats the source of the wire, it comes from right top side of engine, here u see bellow


original hose part number
