if it is noisy, it could be an idler pulley. The 2.3 is very reliable. Balance chains and timing chains seem to last a VERY long time (well over 2x your 110kmi) The problematic 2.3 chains were with the early ones (91-93?) Oil change interval seems to plague the later Saab engines. This is not a reflection on the engine, but a reflection if the extended oil change intervals that Saab recommends. I think it is 10kmi! This is WAY out of line especially with regular oils. Keep it it in the 3k range with regular oils and 5k or so with synthetics and you will be rewarded with a long lived Saab engine just like the older ones... The idler pulleys seem to be a relatively common maintenance item which is overlooked. When you change the belt, I would suggest changing the pulleys as well. Make sure this noise is not a failing pulley... I had an engine noise in my '97 9k and it turned out to be a pulley on its last leg...
