Mreid: the result may not be the same. A chain that breaks altogether may very well cause the valves to hit the pistons and cause all kinds of internal engine damage. Not to mention what might happen to all the chain tensioners/rails and the sprockets when that chain lets loose at 3,000RPM. I was just at a reputable foreign car parts shop and they said the chain and tensioner should run you less then $100. And labor should be around 3 or 4 hours. Pretty simple and inexpensive job that could cost you a lot if you neglect it. General consesus it to get it replaced ever 100K.
