There's no oring in them too.
So is it not a thing anymore? Like, back in the good old days, I was able to remove the injectors off the engine, take them to a shop where they plugged them into their ultra-sound machine, run some special cleaner through them at high pressure (I'm guessing?), and checked for spray pattern and what-not.

Is that it? The only possibility is to replace the injector? End of story?
