Well I installed my sti injectors and started the car but the pass side left injector leaks. Now when i compare it to the stock one and the other sti injector on the same side they look the same.

I swaped the washers and its still doing it. When i put the other one in it makes a pop sound like its in there but the other one doesnt do it. Anyone have any ideas?
Would i need a bigger washer? seal what ever
