Good day,
This is my first post to this forum. I am usually on vintage forums. I have a 62 C10 I am building but unfortunately my 2018 Silverado 5.3 liter V8 101,853 miles on it. The truck started making this noise yesterday. I drove it 5 miles and started hearing this noise when I parked. I took off the three belts and it still made the noise. I listened to all the pulleys with a stethoscope and can not pin point the noise.
I read online there seems to be a problem with collapsing lifters in these engines, is this the noise? See the video below.
If so how do I test what side the bad lifter is on? is there even a way?
I scanned for codes but there were none that said misfires. only codes present were for the UI user interface/radio screen and the tires tpms.

What else should I check? I do not want to go blindly taking the top half of the engine off on a presumption.

Thank you for any advice

sorry only noise and no video image. i converted an mp4 to mp3 to get the noise. I was standing on driver side in front of wheel when recording
