Vacume leak at iac valve

to make a long story short i have a vacume leak at my iac valve on my 99 z28 which i found by spraying it with some starting fluid. i inspected around an removed the valve and noticed that it didnt have an o ring or a gasket on it. is there supposed to be one there and if not how would i fix the leak. Its causing a check engine light to come on, which i have confirmed in another thread.

YEP it should have some sort of seal. IIRC it should have an Oring.

Looked it up in my Helms, it should have an o ring.

Does anybody know if it is a special one or if i can just go and get one that seems like it fits at autozone

I'd try autozone, don't think there's anything special about them. They probably won't know the size though so I'd bring it with me. Other option is visit the dealership, can't cost much either way.

Tried autozone, all they had was were the pack-o-o-rings garbage. i bought them anyway tried em and none fit. ill just say screw it and get it from the dealership.
