My passenger side fender has had oil leaking from it. I figured there was something up with my intercooler, and once I pulled the bumper off my suspicions were correct. The shroud over the intercooler opening had rubbed against it and wore out the aluminum at the three outermost vertical channels. The outermost one has a few pinhole's in it. Which are big enough to allow oil to dribble out and onto the fender.
