Grinding, " diesel " noise under valve covers

The noise in the video is not valve train. ......how many times have I said that now? LOL
Ummm, at least twice? But probably 3...? Whoops. I must be making up excuses for the sound, to alleviate mental issues! Lol... OK. So I'll jack er up, throw some wood under till she's level in the front, torque em down, re check things, toe, and I still haven't cut the oil filter yet
