Well I have done about 20 injectors now without lapping on a plate, just burnished them with solvent on a piece of paper and have not had one leak yet. What does that indicate? Luck?
Edit: Those mating surfaces have mirror finish on them. That (to me) means they are perfectly flat. If they were not perfectly flat, dirt would get in and they won't be mirror finish throughout and leak. So why lap them? If not lapped evenly, a non leaker will turn into a leaker. Why do extra work?
