Thread: Replacing fuel injector tips?

So ive been chasing a misfire and came across this. 4 of them look like this.


Is it possible to replace these tips?
Also could this be my cause of misfire from allowing unmetered air into the cylinder?

That should be fine. The o ring seals still

The tip is just a retainer, doesn't affect the sealing ability of the o-ring. Not that I think so either.
Last I looked, I didn't find a part number for these when I broke one off when I installed my cam, just used an old one from one of the few injectors laying around for the sake of it, otherwise would've ran it without the retainer, just the o-ring.

Well then i need to figure out this misfire.....

I had a similar problem over the summer, immediately after engine work that required me to pull the fuel rails.
