2016 BMW 428I, Wrapping up the turbo coolant lines Part 2, Installing the turbo on the N20 Engine. 

That’s the one on the bottom, u just rotate it from side to side. It has a poring that seals it. That’s the turbo oil drain hose back to the engine block.

It holds up good! I normally use sil glide but I did not have any that day. Been using both for years. It helps you so u don’t pinch the o-rings.
