I removed my 4 injectors and sent them for rebuilding and when they came back the supplied me with 4 teflon washers and 4 caps to slide over the nozzle, i know i got all 4 heat shields out of the chamber with the fuel injectors but i see something that looks like silver washers just before the tiny pipe im to slide the nozzle over. see attached photos, thank you for your help please
