Hello, its me again
Im looking for the part numbers of the o-rings that connect the coolant pipes to the back of the engine through the timing cover. Found some water in my oil, and its the most likely culprit with the insane cold + standing still that the car went through. Im already pulling the engine.
It looks like 07L103121M is the right part, double check it. It is number 12 here.

Full disclosure I only had that up because I’m chasing a leak that looks like it will be the radiator 
thanks, and good luck with that leak

I assume you are referring to the o-rings on these pipes:
