Smoke from engine...no visible leaks

2009 ML 350 94k miles

Yesterday smoke began coming from the rear of the engine. No leaks under the truck, no visible leaks around the engine. (video attached)

It is not a coolant smell, more of exhaust or rubber smell. No visible exhaust smoke coming out of the tailpipes.

Is someone familiar with the likely cause?

Thanks in advance.

Does the gas 3.5 engine have the PCV valve back there?

Pop off your cover and get a better look back there.
