Is there any symptoms of a bad timing chain? If so what are they? Also I was told the lifters rattle...and they do SOMETIMES. I was told to let it die because of it, but I don't want to let it die. The garage people said that because it has as many miles on it as it does to just let it die. (currently over 216,000). But it runs fine other than that, except for a whole in the exhaust which is getting fixed tomorrow.
