Is Mercedes now using Elring gaskets as an OEM part? In the first picture, #2 injector at the prechamber looks great; no oil or soot. Do you know what is causing the wet oil look at #1 and #3 prechamber? It looks like unburned fuel or the cylinders weren't firing properly to get that wet, shiny, and oily look. For the guys saying they will never own that engine. Once they drive one, their opinion will change, I'd bet; and they would be trying to get that thing fixed, bent rods, smoking, using oil and ALL; if that car will keep running like it does when it is running good. These cars will "SLOW", coast at 80 mph. And you can drive 1200 miles in one day and won't even be tired. Get up the next day and drive another 700 miles.
