Sounds normal to me. May want to try a diesel fuel additive to see if you can hear a difference.

I was thinking the same thing with fuel knock, it is best heard the last couple seconds of the video, very faint noise

Hard to say if normal or not over a recording.

if it’s cold weather….would recommend anti-gel and lube additive …reduced fuel flow could indicate as more cp4 noise

its 24 degrees this morning and I’m running a double dose of opti lube winter and have fresh pure synthetic 5w40. I expect the motor to sound very rattle type noisy at startup.

does cold weather effect these engines outside of startup, ie idling in the drive after driving 30 minutes

Cold affects fuel flow …10 to 15 f, as the wax particles form, filter restrictions happen,
