What exactly is it leaking from the mani? Does the "white" smoke smell sweet or like burnt oil (blue-ish smoke)? Check your oil and coolant levels to start with...

i check ed the oil and coolant and there ok the smoke is thick and oil is coming from the top of the gasket were the turbo meets the many. i can see a crack in the gasket, i was told maybe a boost leak or the maf sensor cause a blown turbo wont make it idal like it is. is this true, and if so is there any possible damage that can accure from driving with a blown turbo? can it be repaired if so. i wont be able to look at it till around 430 as se sits on the side of the road

As long as the coolant/oil levels are fine, you should be ok to drive it to a shop or home to work on it. I drove with a S2 RB burning oil for a couple months, but it wasn't as drastic as this. Just be careful to monitor this, especially oil. It sounds like the gasket is gone, along with the turbo going with it. This will probably cause your car to run poorly and burn oil until it is fixed. I just wouldn't boost the car hard until you are able to get in there and replace the damaged stuff. You can't rebuild the RB turbo's because they are ball-bearing, so you will have to buy a new one.

so i went to get my car off the side of the road and it started right up no oil coming from anywhere

drove her home still nothing, called the shop that said it was blown and there like huh ? who knows then. so im searching around and notice the orange and blue wire going to the q45 maf is loose, could this be the caulpret thats messing with me? once again theres no oil coming from anywhere and yes lol i have oil.also my a/f gauge is stuck in the stoich section with no movement up or down, could this be because of that maf sensor, im lost but atleast my worries of a blown turbo our somewhat outta the woods,

Haha...I wasn't saying you didn't have oil, just to monitor it if you planned on driving the car with leaking issues. That is weird though that it isn't leaking anymore through there, but the gasket only seals for boost/exhaust leaks, it is the turbo seals that keep the oil in. I would check the wiring for your MAF, remove the piping that runs to the intake side of the turbo, check for oil residue and shaft play on the turbine itself, and then further inspect the gaskets to ensure they are sealing correctly.
