Default Knocking Sound from 3.6 Pentastar (Audio Sample Provided)

Hi there,
Recently acquired my 2015 JKUR with 50k miles. There is a knocking sound coming from the engine (audio attached). The knocking speeds up when the accelerator is pressed.
I though this might be the ticking noise everyone talks about due to a bad bearing in a rocker arm, but I found this wasn't the case after opening it open. Feel free to have a listen to the clip provided. Appreciate any thoughts or suggestions!
