F150 5.0 Coyote Louder After Valvoline R&P?

No codes and drives great.

In that case I wouldn't lose any sleep over it !
I have listened to the video 3 times and it does sound like a knock of some sort but really hard to tell by listening to a video.

Hello all,
Almost exactly 600 miles ago I did an oil change with Valvoline Restore and Protect. I used the 5w30 variety. Within about a hundred miles, I noticed the engine started to make some more noise while warmed up at idle and low speed. Could be a coincidence, but I just wanted to see if anyone knows noise that is typical for the Coyote engine. Prior to this, it was very quiet, albeit I was using 5w20 and Amsoil.

I would listen UNDER the engine too.
