Timing chain tensioners sound fine, there's a weird whine though that I'm unfamiliar with that is absent in my 2010.

I hear the whine. Much more pronounced on video than in the garage. Goes away around 54 seconds mark of video when engine returns to normal idle. Seems like what it’s always sounded like and I’ve owned from 60,000-120,000 miles. Maybe oil pump? I’ve meet meticulous about oil changes every 5-7500 miles
I was thinking maybe the high pressure fuel pump, but it's been around for as long as you owned it so it's probably not a concern. Do you have a GAP IID tool? I've read that you can check for timing chain slack with it.
My 2010 blew timing around 106k (bought it broken), the timing chain tensioner wore a good 1/4" into the tensioner guides after I was able to tear it all apart. If you have the original tensioners and guides it is inevitable due to poor design.

Did you switch oil brands? I ask because I had the timing upgraded so I know my engine is tight, when I ran mobile 1 the engine made that sound heard in your video, running the factory oil the engine is silent minus the injectors.
