I did a good power wash on my engine compartment a couple of weeks ago. There was a lot of dust stuck to oil on the rubber boot on what I think is the turbo inlet side for the intercooler. It is on the drivers side below the battery about even with the power steering pump. Blue rubber hose about 6 inches long. I noticed today that it is covered in dirt and oil again. No fluids hitting the ground but what could be leaking? Power steering pump seems fine and isn't throwing any fluid.
