I installed 19lb/hr SVO injectors and found that they can be turned in their holes quite easily. Should it matter which way they are turned or is the spray pattern fully symmetrical 3D-wise? Thanks.

 

Yeah it doesn't matter which way they're turned. Just how easily do they turn? They should have a bit of resistance.

 

Well they wouldnt turn by themselvesjust by vibration or anything, its just that I'd never tried to turn my previous ones so I dont know if its normal or not. If the spray pattern is the same then I'm not concerned about it. They're definitely not leaking or anything like the seal is weak.

 

Yeah you should be able to turn them back and forth.
