Hi folks I recorded 2 videos of my 16 Yukon Denali with 6.2L Gas engine 

I am not a mechanic or have the ear to head bad or unusual sound but here are videos of the sound the engine is making.

there is little shake when idling that happens every few seconds and the exhaust is quite stinky compared to my VW Passat 2.0T

Well the valves are kind of loud clacking away. You could have a problem in the valve train assembly
