GMballistic Posted October 14, 2016 Share Posted October 14, 2016 Unless it's making a noise they should last the life of the engine from what I hear, ...the chain that is. The tensioners though may need changing due to wear but again it's not something you hear done very often although it might happen more often now with the cars getting older/higher mileage. The chains though can stretch and if that did happen your timing would be out so it should be throwing up the EML/error codes or at the very least be rattling I'd have thought as if the chain has stretched the chain would most likely be hitting the casing in that case (which causes the rattle from what I gather). I guess with the mileage getting as high as yours is it could be an issue but as you say the timing chain and tensioners have already been done at 90K miles by the previous owner then I really wouldn't worry about it (imo).
