So here is the backstory. My 7 is bone stock. A month ago I started leaking coolant onto the ground near the front passenger side of the car. I did not have time to fix it untill this past week so I just topped it off every time before I started the engine. Never had a heat issue as it was a slow leak and usually took alot of driving/sitting to get it down past the collant level sensor... Also when I started the car it would start up on just the front rotor. There was never any white smoke but got gas smell and black smoke during first startup. After 15-20 seconds the rear rotor would come on and run fine. I assumed this was a leaky injector.

When I pulled the engine bay apart is was very obvious that the hard Y coolant pipe for the turbos was leaking where it connects to the rear turbo. I replaced the two copper rings on the connector to fix this. While in the engine bay I did a complete vacuum hose job and replaced several solenoids and the oil metering line going into the rear rotor housing. I sent the fuel injectors off to be cleaned. The primary injector for the rear rotor was leaking through the bottom o-ring.

Now I have put it all back together and it is sucking coolant into the engine bigtime. It is pulling coolant into both rotors at a very fast pace. I have not gotten a chance to really troubleshoot yet but I have a few ideas. I have read all FSM's all the way through and double checked my coolant connections to make sure I didnt just connect a coolant line directly into a vacuum line. I have also pulled all accessible vac lines (without pulling UIM) and no coolant in vac system so far. I am really looking for others opinions and help with this issue as I am going out of my mind trying to figure out what happened.

Maybe your coolant seals are toast, you could try and do a coolant system pressure check to see if it holds, or looses pressure to help diagnose your problem.

hmm this doesnt sound good. so its actually burning coolant? if thats the case troubles are a comin your way!

Well it would be burning collant if it would start up. It will pull about half a gallon of collant into the engine in about 20 seconds of cranking it. It was not having pulling any collant into the engine before I started work on it. I replaced the plugs right before I started work and they were bone dry. Car also ran fine before I started other than the leaky injector/starting on one rotor. I just don't see how the collant seal went while the car was sitting :\

I have not found a fix for this anyone have a suggestion or things that I should check?

If you really are burning coolant, there is nothing you can do except rebuild the engine. I would suggest pressure testing the cooling system first.
