I still think that it is the fact that you are running rich... however the source of that oil is unknown to me... .I can't think of anything short of the turbo being the cause of the oil... but I would do some trouble shoooting for the cause of that.
How did tunning it go? did it stop smoking or smoke less as you leaned out the idle?

Fc Mania. you can email me the videos RxFC3S@RacingRotary.com

I will host them on my site for ya

ViperDude152: thank you so much, i emailed you =)

jreynish: I havent try tuning it yet , i thought i would just rectify the problem before making the condition of the car any worse if it really is a blown coolant seal..... so u think i should try tuning it and bring it for a no-boost run? after you see the picture of the turbine.... since there is no oil there , do u think i need the oil restrictor still?

thanks

I can't say for sure because if there is a little amount of oil going through at the relatively low oil pressure that is created at idle to 1000 rpm. so Yes I would suggest pulling out your wide band and getting it to idle at about 13.0-14.0 afr while iddling. (orwherever it seems to want to iddle like a champ). I would seriously talk to the manufacturer of the turbo to see if you need a restrictor for the oil line or not. . some of the newer center sections of turbos from garrett have built in restrictors, however some don'tthe only way to know for sure is to call your turbo manufacturer like I suggested to find out.
but I would tune just your iddle down and free rev it (at a stand still) to 3000 rpm and get your afr's just peechy from 12.9-14.0 AFR (wide Band) and then see how the smoke is while you are idling. If it is significantly less then I would start to drive it and check for smoke after higher rpm runs... etc. but the only way to know for sure that you won't blow your turbo seals is like I said above is to contact your turbo manufacturer.

Good Luck...
Let us know.

ok thanks jreynish , so u dont think its the coolant seals cause i really dont want to blow the engine as i have no money for a rebuilt?..... anyone has numbers to call for garrett turbos?

here is one of the videos im hosting for FC Mania

if you have alot of oil in the chambers for some reason that it will put out white smoke. believe me I have had to rebuild compression in my motor 3 times for different reasons and it will just be huge heavy clouds of white smoke

FC_mania

that video is just a similar case of whats goin on cause i cant email my files cause its bigger than 10 megs.... i belief that car belongs to member name vosko

viperdude152: what about premix oil in the chamber then? will it cost it to act like this? im goin to fire her up tomorrow and try to take another video at least a smaller one to ask you guys for help

you say its below freezing correct? well i know when i start my seven in the winter here( can be as cold as -30F) it always spews white smoke... all cars do. when the exhaust hits the cool air it condenses, just like when you breath and its cold out. thats my guess.

FC_mania

any symptoms of a blown coolant seal or an indicator i would need an oil restrictor for my turbo? stupid garrett people say they dont know anything about it and they dont have a technical people to help me out when i called them.

who assembled your turbo?
I presonally thinkn that it is tuning the problem... but just to make sure that your turbo doesn't die prematurely find out who assembled your turbocharger and see if they recommend a restrictor inline with the oil feed line.
Have you tried tuning it yet?

FC_mania

*lol* still havent got to start the car yet. still trying to see if i have a blown coolant seal or not.....

did yours smoke as bad when u were running rich? i mean gods of white smoke that really burns your eyes... =)

i bought it in ebay from this guy and he havent email me back yet.... i will be safe if there is no oil in the i/c pipings , comp side and turbine side right?

i will start her up and tune her tomorrow i think.....shall post the results and let u guys know soon =) thanks a lot

FC mania, give PM me an email I will email you a vid of my car when it was running 10.8 afr at idle.

FC_mania

thanks for the help.... PM u

tune away tmr morning *crosses finger* =D

this forum is so much more better..... everyone is nice =D

FC_mania

new video coming up. surprisingly after i disconnect the downpipe there isn't much smoke coming out or any oil spitting out from the turbine side.... maybe i havent warm it up enough? cause i started it and let it idle for 3 mins....pls advise

there is no alteration done , the mixture is still rich at idle and i havent tune it yet and there is still no oil restrictor on it...... does oil pressure go up after it warms up to operating temp 80 degree C , meaning when its still cold the oil pressure will be low thats why no oil is spitting out yet?

ViperDude152

Aight guys. here is the new video.

http://www.racingrotary.com/movies/whitet2nosmoke.mpg

do you have anything connected to the down pipe? like the rest of the exhaust?

2 stroke wouldnt do this. you couldnt possibly put enough in your gas tank to make it smoke like that.

Justin

FC_mania

erm before i took the dowpipe down... its just connected halfway until the mid resonator lol.....

so does the oil pressure go up after warm up? cause i dont know if i should pop the restrictor in cause funny thing was without the downpipe on there seems to be no oil or gobs of white smoke

FC_mania

no one knows?

ViperDude152

well when the engine is wamed up. and while you hold the engine at 3000 rpm. the oil pressure is supposed get to 64-78psi. I dont remember if the oil pressure raises or decreases with the engine cold. I do belive it decreases though. my oil pressure sending unit hasnt worked for months so i dont know my oil psi and cant monitor it right now. But I think it does decrease as the engine warms up. but that is probubly mainly due to the fact that the engine is near 2500 rpm when cold and so the oil pressure is high. till its falls to idle and the oil pressure should be near 30psi or a lil less
