Looking to buy one of these guys, don't really want to spend $30 on it right now for a new MB one, got to buy some books but I need my car running again.

It is this guy, I need it for a 603, but I believe the 602 used the same one. Should be on 300D, 300TD, 300D 2.5, 300SDLs


I pulled this pic off google, bottom right. It is the tube that runs from the valve cover down to the turbo intake boot.
