i replaced the motor on my s70 and i have an extra vacuum line. i'm not exactly sure where it goes. any ideas? thanks!

 

It looks like it might connect to the back of the airbox? Maybe? I'm not totally sure... lol

 

I am so frustrated with this line!!! I did the motor during the summer and I have not driven the car yet because of this. I have a 98glt that had a bad turbo, so I changed it turbo during the winter, with a 16g, and my help put on the lines to the bcv wrong, I blew the motor that day. When I replaced the motor, I found a 2.3 from an 850 to use, that only had 118,000 on it. Better than the 223,000 that I have. Now I am hesistant to take it on the road until I figure this out. The car runs so nice and I have not even enjoyed it yet. I even have a 3" exhaust from the turbo back. The car sounds nicer than my woman's SRT4.

 

I have had my PCV lines out and have not seen that one. Look at the throttle body area and maybe the cruise control. There is also a tree under my MAF.

 

Today I found a hose like that going into an electrical sleeve near my fire wall. The bigger end of the clip is attached to my AC freon tube that goes into the fire wall and the thin tube goes from inside the wire sleeve closer to the finder and the other end goes down along the AC lines and I can't see the lower end. Hope that helps. Let me know if you need a picture.

It also looks like the vacuum line that connects to the cruise control under the battery box.

This is on my 850 R, my S70 is not around, at college.

 

I saw a line like that coming from the Bypass valve on the Turbo. It comes off the valve and then comes up along the back of the engine where the sleeve connects to another black plastic hose.

 

I am going to take a look again this weekend and see what I can find with your suggestions. When I was taking the motor out I found this line laying on top of the transmission. You guys had mentioned something with the cruise control which I find interensting, since mine has not worked in years. I hope I find it. I would like to have it on the road next weekend. I will let you guys know.

 

I was unable to see where that line would be coming from the firewall. Can you post that picture? That would be a huge help.
