You got lucky avoiding #YNANSB. That bearing looked to me initially as antifreeze damage. That was from my ancient memory. But after researching I think:
This seems to be a good place for this.
After losing a rod bearing I disassembled the VVT sprockets to clean out the debris.
Afterwards I had a P0018 code after running awhile. It turned out the variable cam timing sprocket on bank 2 had bound up on the cam.
I noticed when I assembled the sprocket to the cam it didn't slide easily on to the cam. The 2 bores of the sprocket can be assembled non-concentric.
I removed the cam and disassembled the sprocket, reassembling using an old cam to assure the concentricity. So far so good.
I'm sure this has been discussed but I haven't found the correct search. Has anyone thought of a community lifter collection. I have 10 lifters after doing my engine that I would be willing to swap out for different sizes (the person needing the lifter would send their trade ins' and pay the shipping). Just a thought.
Maybe this :

235,000 mi on my 2005, rebuilt the turbo due to oil consumption last weekend. The power steering is noisy on the cold mornings, a lot of those this winter.
