Timing Chain Question

Negligible difference though. When you say Toyota timing chains are so durable, do you mean it may not need changing for another 100k, or so? Would I get some kind of warning before it goes, like a rattle or a stuttering engine?



Very grateful for all the help by posters!

Timing chains typically outlast the lifespan of a car, with a few exceptions like Audi's 3.2L V6 which have a premature wear of the tensioner...
