what is this noise
trying to diagnose this sound coming from the engine.
the sound starts at about 5 seconds into the video, but almost 4 minutes after engine start. https://photos.app.goo.gl/jLQ5aaecn4pUW5LL6 some relevant background info: -had a serpentine belt failure in June -removed belt pieces from pan and pickup -replaced oil pan gasket -installed a front main seal protective cover -added oil accumulator with check valve -no codes present in mhd

If you rev the engine slightly does the noise change? Any metal particles in the oil filter?
Also did you remove the valve cover and check for pieces of belt in the timing chain?

I didn't find any belt in the timing area. I checked my oil filter... looks like glitter... son of a bitch.
welp.... my LS swap will begin earlier than anticipated!
