help needed asap (turbo)

[live4my4g63]

i just started my car for its first time and i got a turbo from a friend that is on there now so its used. i start the car, idles a little bumpy, then smoothens out, soon as it went smooth it pumped white smoke from my downpipe (its open) and not its leaking black oil from the pipe. i checked the oil and its not milky so i dont think its a hg, i think maybe the turbo is bad, my friend who is a mastermind with these cars said it could be the motor doing that for a start up saying some do that, what do you think it would be

what turbo did you put on?

 

[viperlp01]

It could be condensation but it should go away very soon... How much oil is coming out??? Is there any shaft play on the turbo you used???

 

[GsXdSmKingGsX]

if you JUST put it on its going to have some oil in it of coarse. it could just be moisture

What sort of "top secret" turbo are we talking about here, since you've failed to complete your required profile information?

 

[GsXdSmKingGsX]

justin to the rescuuue!!

 

[viperlp01]

ya his mods list is to big so we must keep it a secret... I hate when people do that.. I understand if your running 7s in the quarter but if your car is a 14 sec car why try to sound like its fast..

It sounds to me like the turbo's getting too much oil pressure, but without information like what kind of turbo it is or where the oil supply is being fed, I can't even give an educated guess.

hey i had all that listed with my senior project build with a t70, but this is the link to my turbo
Turbo Elements - #1 Online Source for Garrett Turbos
i have the line fed from the oil filter housing, i was talking to my friend and he was telling me what could be the issue also, on my return there is about 1.5 inch of 5/8 size line and then its reduced to a 3/4 i think it is so it is a thin line running to the pan, he believes that it might be backing up the line trying to rush into a smaller line like a funnel when being filled to fast, and to answer one question, its alot of oil being pushed out of the pipe

That sounds about right

Yeah, your restrictive oil return line sounds like it might be your issue. If the oil can't flow out the drain tube, it will start coming out your shaft oil seals.

now everything flows fine, i still have oil burning through the exhaust and leaks all around the middle section where it bolts up to the two housings, could that mean i need to rebuild it

Do you see any leakage from the compressor outlet as well? If not, then your oil feed is probably ok. I would take the turbo off and check to make sure there is no oil in the turbine housing inlet. If there is oil in the turbine housing inlet that means you have oil coming from somewhere in the engine. If the turbine housing inlet is dry and turbine wheel/turbine outlet have oil in them it is most likely a turbine side seal problem (as long as the possibilty of an oil feed issue has been discounted).
