So 1 injector out of the 8 stops leaking oil out of the spout after 5 minutes? The other 7 injectors keep leaking oil?

I can't find a thread on replacing injector sleeves, (have the sleeves from Rock A) so this was in the same area so here goes.
What seals will I need ? I've never had this apart before so just after some info. Doing the job at a mates workshop (Ex Cat & Cummins fitter) so can call for assistance with the sleeve removal tool.

Couldn't put this off any longer. Started the injector sleeve replacement job today. Searched multiple "youtube" videos on the subject, trying to remember all the odd bits to do as I've never been inside one of these engines. All good so far.
