Ive been looking around under my hood looking for possible vacuum leaks and found this. I need to know what it is so I can replace it and finish problem solving

 

Hmm, picture might help...

 

Sorry to say, but I looked very closely at my cars for hours today, and nowhere did I find the RED X device. Sorry 'bout that.

 

Lets try imageshack lol

 

Its one of the solenoid valves. Cant remember which one blue is. The nipples break off all the time. Put up a wanted to buy in the sales section. They can be cheap and/or free.

The blue is the Relief solenoid. If you plan on getting rid of your emissions at some point, I believe you can get rid of them all. I did on my turboII, but for mine I had to keep the green. Which you probably don't have since it looks like you have an NA. But this is the thread from when I posted a similar question. Maybe it'll help
