2012 ls3 engine tapping

I have a 2012 LS3 that's has started to make a tapping sound while idle. Gets more noticeable once it warms up but isn't very loud to really concern me but would like to know if anyone has a idea what it could be. It's not consistent but goes like tap pause tap tap tap pause tap tap and so on. Anyone else have any kinda noise like this?

If it gets worse when warmed up lifter or rocker arm issue. Get to the dealer.

Have you considered getting technical assistance from your dealership? They should be able to check this out properly for you.
