rear injector no needle tip?
I'm assuming there should be a needle tip on the bottom just like the other 3 injectors I did. I need to replace this injector?

Yes. If it's not there that is a problem. I would recommend a set of injectors from idiperfomance.com, rather than individual replacement. They are a maintenance item.

If they have grey paint they are OE. The injectors are carefully calibrated to open at a certain pressure, which has an effect on the timing when there is a variance between the injectors. If an injector has a low opening pressure, it will fire minutely earlier than the others.

​​​​​​​I just changed all the orings and crush washer and they looked ok plus I just ran seafoam and diesel klean not to long ago. BuT I don't recall what paint they were but someone was definitely in there before. A few orings were green or black or brown I'll replace all injectors in future. When I drove her home a few months ago I had 0 issues. Purr like a kitten. Then the air intrusion started
