bad injectors ?

Just wondering how noisy injectors can get when going bad..

I'm asking because , I started hearing a ticking noise, thought it was a valve/rocker, but then I did the old screw driver trick .put it on valve covers, nothing, on super charger, nothing, put it on the fuel rail sure enough loud as could be..

The noise is so loud I can hear it in the cabin..
Any thoughts thanks mike

It is possible for an Injector to be that noisy. Very, very possible.....

Not sure it's a bad thing, since I want to get some 42.5 anyways...
