This is a bad headgasket right?

Another concern is where this oil is coming from in your intake. Your PCV valve not gummed up and working properly? As if it stuck open I am wondering if your sucking some oil into it via that hose.

How does your throttle body butterfly look? Really carboned up and nasty? I am thinking that pcv valve hose hooks into near or right after the throttle body.

I’m almost positive it’s related to a busted PCV, see it when BMW’s all the time. Plus cracked vacuum hoses, it’s like I never left!

TB is dirty and I can see oily residue in the intake manifold

That would be my guess on the PCV valve and why your throttle body is all oily and why the oil came out of your air intake hose.
