View Full Version : How to tell if Timing Chain Needs Replacing

04-09-2002, 09:02 AM
I have searched for all related timing chain information, but there is one bit of information I can't seem to find. How does one tell if the timing chain or any of its components need replacing?

I have a '93 with 150K miles and the timing chain has never been replaced. I do not have any noise coming from a broken tensioner or any other symptoms of a failing timing chain, so what I am wondering is how to measure if it needs replacing before it gets to this point?

people don't usually have major problems with the DOHC engines as far as the timing chain. if you start getting rattle at startup or before the car is warm, that's probably because your tensioner is going. if you really want, take off the valve cover and check if the chain is really slack (REALLY slack, it'll be a little slack normally) after the engine has been off for a while and see if any of the guides down in that area look like they are majorly scarred, cracked, broken etc.
