I had a timing chain fail at about 145K, it was not a "good thing". Also, have them inspect, and most likely replace, the chain tensioner. A week after my timing chain failure, the tensioner broke and that was pretty bad too. I changed mechanics after that episode, because in my opinion, they should have gone to the extra hassle (10 mins) to check it the 1st time. - Levi In article <3B36097B.A77DA6DEnopsamia-espreZZo.com>, danny <dannynopsamia-espreZZo.com> wrote: > My local Saab dealer tells me that timing chains rarely break (at least > on the 9000, I didn't ask about other models).
