started my car for the first time
well today i got the turbo drain lines sorted out and the transmission cooler lines done, so i decided to fire the car up, before firing it up i primed the motor, basically i took out the fuel pump relay and ignition relay and turned the motor over with the starter until i got about 50psi of oil pressure, that went well, no leak or anything,
so then i placed the relays back and fired it up for real, first crank and it fired right up, but there was a **** load of white/light blue smoke pouring out of the downpipes and when i look at the downpipe it is puking oil out of both of them.
my turbo drains are on a good slope and should not be a problem
my engine only has about 6000miles on it
the afr was pretty rich 18 something at idle
turbochargers are brand spanking new turbonetics units
my oil was at about 75psi as soon as i started it up
i did not have a chance to look at the plugs yet because my garage is full of smoke and i do not want to die yet
so why would my motor be puking out so much oil ? is it because i primed it before starting it ?

^^^it is a custom twin turbo kit
do you think that afr ratio will do any damage to my motor ?
it shows me that afr as soon as i started the car and as soon as i touch the throttle it goes to 13.1, and i never gave it a chance to warm up so maybe the sensor is giving me a bad reading till it fully warms up
it will try placing the feed lines so they drain back in to the valve cover and hold the compressor wheel from spinning and we will see what happens. thanks for the help

Also, you have to restrict the oil feed to the turbos, not sure I saw that from you there. 75 PSI of oil is WAY too much and will cause it to smoke and get oil in the "exhaust". Ball Bearing Turbos need oil just not an insane amount of it!
EDIT:
Also, what were you using to get your readings at idle? I am not 100% sure on this but don't you have to warm up your wideband O2 sensors before the fire the car up (turning the key and letting it sit for a couple seconds) before you fire the car up?
Don't quote me on that last part....just what I have seen done in the past.

Most widebands are reading correctly within 5-10 seconds of having power put to them. 18:1 shouldn't do any damage, but if it is richer with throttle I would be giving it some throttle. If you have hptuners you can add fuel in the scanner under vcm controls, not sure about efilive.
Most ball bearing turbos come with there own restrictors.

looks like it started to clear out when i let it run a little longer, going to run it again today and see how it goes
i wideband sensor is not ruined from all that oil right ?

measure youre oil pressure at idle and at WOT not just with the engine cold, do a hot engine as well since the pressure will drop.
For starters what oil are you running? simple things such as swapping out oil can stop turbos from smoking, now if it was the first time, chances are the turbos had some oil in them from the factory to keep everything properly lubricated, since you mentioned its going away with time?
Again, too much restrictor means ur turbo is getting less than adequate oil flow, and too big will cause the smoking issue, so again based on a few factors get something properly done, also restrict the oil feed lines NOT at the turbo, but at the t-fitting on the motor.

The oil you're running isnt too thick either, fully synthetic??

And you want to VERY quickly get your car idling in the 12-14 AFR range. 18 is too lean, and some widebands won't register any leaner than that, so you could be at 20:1 for all you know.
I wouldn't think your short running time has done anything bad, but get some fuel in there ASAP.
