I have a '78 Buick Regal with a 3.8l 231cc Buick V6. The Chilton's says to replace the timing chain at 120-150k. The car has 133k. I've been told not to worry, but I understand that if the thing breaks it can trash the engine. What would you folks advise? Does it give much in the way of warning signs before it goes? Also, would getting a new chain improve performance?
