2015 Malibu Intermittent Cam Noise?

I recently changed the belt and tensioner as I thought the marble-like rattling I hear came from a bad belt or tensioner. Unfortunately I am still having intermittent rattle that increases with rpms. Doesnt make noise all the time. Sounds like inside cam cover?? No mil codes yet. I need to research this engine to see how to troubleshoot the noise. Any help is appreciated as I don't want to damage engine.

It's a 2.5L Eco nonturbo.
