how your engine hanging? How many miles since then?
Mine was making the same sound which disappeared when rev was slightly increased from the idle speed when running on 5w30 oil.
After the 5w40 oil change i am getting no audible noise, only using a stethoscope i can hear the same noise.

The sympthoms are the same as yours.
