I will remove that hose and take a gander. The couple of times I've had it
off in the past, there was oil inside the hose, and there would pretty
consistently be some oil in the ribs of the "Michelin Man" hose, but I was
always of the impression that was not necessarily abnormal.
Maybe a "before and after" is in order. Look and see what's in there, empty
the hose, let the car idle for a long long time, and check again.
