This valve lash, I am pretty sure was deemed harmless by the manufacture. I remember a while ago when this issue came up on here. Someone posted a TSB for it from Dodge regarding the issue and the fix. I googled for a while and came up with this
2004 DODGE NEON TSB 0900704 Details
My car does this too when the engine is cold, then goes away. Been thinking about taking it in, but I hate letting anyone touch my car.
