E92 Uncommon Lifter/Valvetrain Noise

[filmy]

Yeah, after further research and consideration my lifter noise isn't so unusual, it's just more severe than most. After listening to a few other videos, I could tell they have my exact noise; that is, the normal mild ticking plus one or two louder "knocks," which probably means I'm in for a lifter (HVA - hydraulic valve adjuster) replacement if my oil change and a couple of additives (plus some spirited driving over a month or two) doesn't automatically quiet them down.
