deccelaration tapping, knocking

My truck makes a light tapping, knocking sound when I let off the gas. I have had 2 1 5spd & a auto & both do it. This normal valetrain noise? You can only hear it if listening closely with ac & radio off.

Can you describe the noise in more detail?

If its what I think you're describing, it's normal...but I could be thinking of a totally different sound

Best way I can explain it is a sound up on top, I had another truck that made the same sound 20k miles later it didnt get louder. Just want to make sure it aint a rod/wrist pin or bearing. Do those start of slow or all of a sudden & bang? I have a video of the sound on another post in this section under: Knock!
