(it was > noisy at 75k). The chain is not "due to be replaced" at 100k miles or any other specific distance. The chain should be replaced when it has too much wear. One of the criteria is if the tensioner has advanced beyond a certain point. This can be checked by removing the valve cover. A noisy chain is not a signal that the chain must be replaced as the noise can be caused by a tensioner that is not working properly, or be due to the way the tensioner works. The tensioner in the 9-5, for example, advances in steps, so the chain may be noisy from time to time. -- G–ran Larsson http://www.nospam.com/saab/
