It's definitely the injectors. I got out the stethoscope just now and touched to everything. Injectors are making that sound, some louder than others.
Loudest being the #1 and #7.
With the scope on the valve cover it's super quiet. So that's good. Touching the intake bolts I could hear it but not even close to actually touching an injector
