Although, frankly, I'm in the middle of a noise hunt too and it could be one of several things. Balancer chain getting a little older, sticky valves (sludge in the oil system), alternator bearing starting to pack up, water pump starting to erode, belt tensioner starting to pack up, power steering fluid in need of a change, AirCo clutch sticking. Just simple leak somewhere in the exhaust manifold, cat or joints. Your best bet is to get a mechanics stethoscope with a probe and carefully try to track it down to source, I keep one in the tool kit actually. Hit saabnet.com 9000 bulletin board and search on component/noise for further detail as you go. Given it's a new/used car to you - it is worth being very careful to check everything for correct torque, gap, resistance and flow. Not everyone is above leaving something for the next owner and it is good practice to try to fix things in the 9000 *before* they fail outright and destroy the more expensive complete component or system they are attached to. The upside of this approach (and the 9000 line in general) is that it can be relatively inexpensive to fix a smaller problem in a given component before it fails and the fix will often last the lifetime of the car in your hands. -- Radio Free Dexterdyne Top Tune o'be-do-da-day Sinatra Dean Davis - That Old Black Magic http://www.dexterdyne.org/888/102.RAM all tunes - no cookies no subscription no weather no ads no news no phone in no sign up required - all the Time
