    I changed all the o-rings on my injectors a week ago. Yesterday #4 started leaking so I popped the rail off to re-seat. All the injectors came out with the rail and popped out of the manifold as well. One of them the o-ring and the little plastic(?) collar below the o-ring came off and were down in the manifold opening. I was able to get the o-ring but the little collar went through and is gone forever. Do I need to replace that thing? There are no leaks now after reassembly.

    So the plastic piece is stuck in the fuel rail?

    No, it went down the intake. I have no leak currently, but I am guessing that is a very real possibility in the future. I also figure that little sucker went past the valves and is melted in the cat converter.
