Done a few hundred miles in my Forester this week for work. Going to lose my licence at this rate though as overtaking is to much fun. (Safely of course.) Did notice while at the drive through for McDonalds the when idling it was making a weab, weab, weab noise. Sounds like a belt but it increases in frequency as I increase the revs. Don't really hear it driving at speed, just when stationary.
