Need Help!!! Vacuum Line Hell!!!

Need Help!!! Vacuum Line Hell!!!
Aright so heres the deal,
a couple days ago i decided to replace all the vacuum lines in the engine bay since all of them were pretty much rock hard and cracking.
My buddy came up (RotaryBred) and we yanked the UIM off and the solenoid rack. After about 3 days of attempting to get everything working and breaking like 4 solenoids, i replaced the solenoids with a set from a friends car and we started putting everything back together.
About 6 hours later everything seemed to be back together except ONE vacuum line which on the FSM diagram and different coloured diagrams from the net, just seems to disappear into nothing.
That aside, we attempted to start the car up, and after 10 - 15 attempts she started up, idle was normal, no misfires nothing, BUT there was huge amounts of white smoke billowing out the tailpipes, im assuming coolant because of the sweet smell.
So now here we are, 20 hours into the project with NO idea what to do now. We're not sure what we did wrong, we followed the diagrams and used the FSM and beyond this one vacuum line and the smoke, everything seems normal. Before the break down, there was no issue with the coolant so im at a loss.
Someone, help me out!! please xD

just to add... this one vacuum line comes off the intake elbow at the front of the primary turbo, hooks to a metal pipe that comes out the other side under the oil filler, and exits out the side slightly diagonally forward. there are 2 lines coming off this elbow, one is small and one is large. this is the large one that leads to no where in the vacuum diagrams. actually in the diagrams, it shows it plugging right back into the exhaust manifold. this doesn't explain the mass coolant burning though.

i checked a diagram, and could not find this hose you are speaking of? are you sure it was a vacuum line, i dont remember a line coming off the elbow? hear is the largest diagram i could find, i hope this is of any help to you:

i know how you feel, i replaced alot of my hoses...pain in the ***. broke a soleniod nipple and some hoses got pinched after putting the plenum back on! didnt have it running for a month. hope you figure it out..

That one goes to your oil filler neck and from there to the nipple on the front of the UIM, I have an oil catch can and I have that line going from the elbow to the can and removed the line and capped it from both the filler neck and UIM. As for the other line that one goes up the rats nest as well than "tee's" off and goes into both housing.

Hitokiri,
There are two hardlines (joined together) which run across the front part of the engine. They supply coolant for the turbos as well as venting for the oil system. The bottom line from the oil filler neck connects on of the hardlines on the driver's side. The hard line runs over to the passenger side of the engine where you then have a rubber or silicone tube connect it to the nipple on the primary intake elbow.

The one Mahjik is indicating is the one that shows on the diagram that goes to the elbow and T's off into the housing, thee other one goes to your filler neck....

If it is possible to do so, I'd think you somehow have the one line that feeds coolant to the turbos switched with the oil vent line. So instead of feeding oil system venting into the primary turbo tubing, you're forcing coolant in there.

hrm... well beyond the two lines that lead to the elbow before the primary turbo, we didnt touch any lines to the turbo, everything that was replaced was at the actual solenoid rack.
The only actual coolant lines we touched where the ones that lead from the coolant filler neck to the Throttle Body, beyond that everything we did was all vacuum line.
From it just sitting for four days is there anyway i could have possibly done in a coolant seal?

It's highly doubtful that your engine suddenly lunched a coolant seal just by sitting there, and you can't just lunch one starting your engine up. Everything points to a mistake with the vacuum hose job somewhere.

Constant threat
Would it be possible that something in the throttle-body coolant fitting broke and is letting coolant into the engine?
I'd go rent or borrow or purchase a coolant system pressurizer and listen for leaks.

Well, all it would take is pulling those two lines off the primary turbo intake tube to see if there is coolant there, and even if there isn't, tracing the lines back to be sure. You're going to have to take some of that stuff apart anyway if you're "just gonna start putting together a single turbo kit and getting rid of all that **** cause its ridiculous."

eitherway, imma pull the solenoid system apart and see if i can find anything to point to it not working.

How will the solenoids have anything to do with it burning coolant?
