timing chain noise on 2000 Nissan Maxima

Yes, sell your car and replace it with something other than a Nissan... they're producing INCONSISTENT quality....

Once they start to go, isn't much of a remedy other than replacing it. Most likely you are hearing the tensioners, but you may as well replace the timing chain and sprockets too.

I thought that "timing chains" were supposed to last the life of the car??? Obviously, this isn't true and if I were you, I would find another vehicle..

How much is this going to cost? Usually, timing chains are much harder and more expensive to replace than a timing belt...
