Injectors

[02AleroEco]

So i had my hood open, cuz i had to add more washer fluid and was just checking the over fluid to make sure they are good.

And i noticed black, kind of like something leaking but half drying type color if that makes sense around my valve cover i believe youd call it. (02 Eco) But more so around my injector area. one and sort of the one next to it on the side near the belt and im suspecting that the o rings might be bad?

i can get a pic later if you all need.

But i was just wondering how to i remove the rail to get at the injectors so i can check the rings, because if i recalled correctly each injector has two of them.


Also an edit: i started the car a little while ago because i had to run downtown, it smelt like fuel. but it started fine no real hesitation. then the fuel smell went away
