Ok, I was looking at my friends 97 4.6 and I noticed somthing different on his Intake, there is a vaccume line on his where on mine it is capped off. Im not sure if I have somthing hooked up wrong but If you guys know if this fitting should have a hose or not and where it should go, please inform me. I looked on his engine and it looks like it goes to a plastic peice near the cowel. So I checked mine and on the back of the intake there is another tube and thats where I have a hose going to the same plastic peice. So I find out his has the same tube in the back of the intake and it goes to a line that I have connected to my PCV, because thats where it was connected before. Am I supposed to have one line off my PCV or 2 and if not does the smaller vac line thats currently on my PCV connect to the tube on the back of the intake??? Here is a pic of the tube I have blocked off.
