I have a 2012 Traverse that my daughter drives, and it’s making an inconsistent rattle in the top end like there’s something bouncing around in the top of the head. There is also a deeper knock that comes and goes that sounds like it could be lower end. Has anyone ever had a similar problem or has any idea what it might be?

Wed probably have to hear audio.
Some people describe a tick- but its the High pressure fuel pump- usually very audible at idle. so yeah-- audio/video would be good

that is definitely NOT the high pressure fuel pump...
I wonder if oil passages have clogged and not allowing proper lube of some of the moving parts up top.
