What is this thing on my valve cover?
99 SLK230 Kompressor and on the passenger's side of the valve cover there's a black box. It's flat on one side and round on the other. It has a hose that runs from the valve cover to it and another that runs from this box to the air filter box.
I assume this box is something along the lines of a PCV? I'm asking because my g/f's car has a lot of oil in the air intake tubes and I traced it all the way back to this box and valve cover. I need to see if I need to replace that box or what the deal is.
