Fuel injectors leaking!

[1975300D]

Well, I got my fuel injectors reassembled, but unfortunately, three of them leak.

I did the lapping procedure and I also made sure they were nice and clean. I also blew them out with compressed air.

Yet, two of them at least are leaking at the return nipples and two are leaking at the body joint.

Will these leaks tend to seal themselves with time?

Since the nipples are not serviceable, does that mean a new fuel injector is required?

Thanks

I had mine refurbished by the whichunters group because they test them to decide IF they can be rebuit. They will not stop leaking on thier own
