7.3 Injector question. Does this look right?

Bought a set of used injectors to install in my truck.

I was cleaning them tonight and noticed that one of them had one of the four holes at the bottom open.

If you look at the injector, there are four holes towards the bottom, one on each side I guess you could say.

On all of them I can see a little piston assembly but on one hole it looks like it is opened up.
Can that be normal? What are those holes for?

I am hoping you can tell by the pictures what I am talking about. The top picture shows the open hole, the other shows what all the other holes look like.

That is how the fuel gets into the injector. The upper holes are for oil to get in there.

So it is normal that one hole might be open and the others might be closed?

I'm not sure on that one... I'll look at my 9th injector today.
