Re: replacing rsx timing chain
just replaced mine 2 weeks ago for the same problem, you need to change tensioner as well. I also replaced the guides as well with the chain.
For the record honda claims timing chains are good for life of the car. I noticed streching in my old chain.
The job is about a 5-6 hour job but I found it to be a pain. since honda decided not to give much room to get down there.
