That start-up clatter you describe sounds like a cam phaser issue.
Maybe. It's not dramatic. But, I can definitely hear a difference in noise that maps to the time period where logs show very low oil pressure.
I'm still shocked that we can't all agree that the less time an engine spends running with low oil pressure, the better. This is a fundamental truth in my eyes. But welcome to the Internet, where supposed "locked in experts" will call that "idiotic".
