Smoke in the engine bay of a M112/113/K car is commonly caused by the valve covers leaking (either the gaskets or the RTV in the sealed upper sections) but there is no way to confirm that with the limited info you've provided.
Does it smell like burning oil? Any issues in how the car runs / drives? Any warning lights?
On a cold engine, remove the front cover and the air boxes, and start examining the valve covers / surrounding area with a powerful flashlight.
You're looking for leaks as a starting point.

Many people have issues with leaking valve covers. First issue is to only, ONLY, use MB valve cover gaskets. Second buy new screws for the upper cover. Follow tightening torque specs exactly. And, here are a couple of videos that Tasos has done specifically on some of the issues of the M113 valve covers and the casue of leaks.

Like others have said, 99% chance it's a leaking valve cover gasket. Every single one of these engines will have that leak eventually.
And your engine bay looks meticulous so I'm sure the car has been well cared for. Do not be concerned. Just have the valve cover gaskets replaced.
