Hello everyone!

Reading the posts re timing chains, I still am quite unsure as to what REALLY causes that seemingly sturdy part to go bad/stretch... So what does?

Secondly, what are the symptoms of having abnormal/out-of-spec chain? Is it possible to immediately recognize this problem?

Lastly, is changing the timing chain a DIYer? Or does it require some special tools which are hard to come by?

Thanks again!
