Which hose did you check? The driver's side on mine was nearly spotless as many others have reported. The one that's problematic is the passenger side.I changed the oil today @10,000 miles. I was on tenderhooks wondering if I had the same issues as others have reported, although the car has never exhibited any symptoms. I'm happy to report that despite driving the car thoughout this particularly horrible winter I did not find one drop of anything in the intercooler hose.
