Bad Injector Pics

Despite my superior searching skills (yeah right) I cannot find pictures of what the typical injectors look like after removal. Specifically, what I'm up to is: I removed the injectors from my truck and I would like to see what a comparable set should look like. Just kind of a "here is a good looking injector, here is one that is shot". Anyone know of something like this, or a good description of what to look for without disassembly?

Here are some pics of good injectors with bad o-rings.
The Smoking Gun --

But generally, you won't be able to tell a good injector from a bad injector. Well, unless the nozzle is broken off.

The only real way to tell if an injector is bad or not is to put it on a flow bench and flow it and to take it apart and masure its specs.

IMO send them to a GOOD injector shop like Nate at Unlimited Diesel or Cass at Full Force Diesel to have them looked at and flowed and rebuilt if need be.

Thanks for the replies; I removed my injectors, due to a long standing crank but wont start issue. I am going to send these to a well known 7.3 specialist, but I was just hoping for some type of flashing neon sign that says its bad. I figured it would have to be disassembled, so thanks again.
