I am trying to get everything put back together from replacing the PCV system. I am trying to figure out where the vacuum line that connects to the flame trap goes to. It is #14 on this diagram, http://www.fcpgroton.com/product-exec/product_id/18590/nm/1993_1994_Volvo_850_PCV_Breather_System_Kit/category_id/63

I see nothing on the intake manifold that this would connect to besides the fuel pressure regulator and the vacuum control for the variable length intake runner system, but I already know what goes to them.

Ive tried looking at the diagram under the hood, but I cant tell if this vacuum line is even on it.

 

That's why I cut my lines so I would know what went where. Does this picture from my car help?



I believe #14 is the one that goes on the side of the intake manifold kind of below the thermostat and under the power steering. Not positive though.

 

I usually keep the lines either in the same area they came from or at least connected to the old components, but this one must have been misplaced

That is a turbo I think, and is different from my N/A. I did get a reply on another Volvo forum saying it goes to the vacuum tree on the intake manifold near the throttle body. Someone else mentioned that it goes to the manifold by the power steering pump, but there is no ports there on mine. Maybe it does on turbo engines

Let me know if you think what the other person said about the vacuum tree sounds correct.

Edit: Sorry, I forgot to say that this is an 84 N/A.

 

That could very well be where it goes.
The port on the end of the intake is on turbo or Non turbo cars. But not all have it.

 

Sorry didn't realize yours was non-turbo.

 

Yes,
If your manifold doesnt have the port at the powersteering pump side end, then this line shoud go to the port on the tree next to throttle body.

 

Its all put back together. It was pretty easy except for some of the hard to get to bolts. I have to wait for my oil filters to get here so I can change the oil, then I will see if it runs. Hopefully it starts and runs fine, I just want to drive it!!

Thanks for the help!!
