I am concerned about my timing chain. My records show that it is original (340,000). My manuals/CD do not show how to check for stretch, or I just can't find it. I intend to replace the chain itself, next spring when it is warmer. If my chain is loose will it be obvious aurally, and especially with a stethoscope? Does anyone use offset keys to correct the stretch anymore? I see that to change it, I attach the new one to the old one and rotate the chain around very carefully. I will replace the chain tensioner, should I also replace all the rails? Let's talk timing chains!!!!
