Ditto what mike said....replace all 6 of the retainers while your in there also if you replace any of the injectors you may need to record the calibration number of the injector into the PCM, if so make sure you write down the number of which injector is in relation to the cylinder. If you don't the PCM may set a code and turn on the mil.Of course this is based on my experience with the dodge trucks, don't know if the system you have is similar to what I'm familiar with.
