Thanks Larry,
I have all the factory manuals, and I have seen that procedure. I guess I need to keep looking. Do I need to replace the three different rails when I replace the chain? I would be less reluctant to change the chain and most likely the tensioner at the same time if I could leave the rails alone? Are my rails likely to be worn if they have 340,000 miles on them? Thanks for the response. I was wondering where you were. Welcome back!
