How long since you started the car? I just finished my rebuild and the car is obviously going to smoke on first start up. This is normal to burn off extra assembly glue or whatever. I don't exactly know how long that is supposed to last for but it should burn off.

Also, if you're starting the car for the first time in the morning, are you sure it's just not normal exhaust?

i heen driving the car for more than a moth now. is been setup at 20psi right now. car runs nice and strong. i think might be the oil is leaking or somethings. it just been too lazy to change the oil injector . just want to see how they work first before i start taking it a parts.

I'm not the best person to get your knowledge from, but see what kind of smell the smoke is to see if you can tell if it's coolant.

Did you rebuild yourself?
did you get the oil control rings and springs in the correct orientation?

There is an Oil Metering Pump, and it receives an electrical signal from the ECU, and that's what regulates the Oil Flow into the motor.

Have you tried to use heavier oil, I tried to use very thin oil thinking it would be better for the motor as far as lubrication went, and it was so thin the turbo seals didn't hold it back and I had all kinds of smoking issues with the car, figuring it was the OMP I messed with that, and it ended up all I had to do is use heavier oil...

Yes but did you put the rotors in the correct location? Even if the rings are installed correctly if, after puttng the rotors together, the front rotor is put in the rear housing when assembling the stack the rotor will spin in the opposite direction to keeping the control ring springs in place. The result - Smokey Mcfogger will be your cars new nickname.

10w40 thats what i using right now

That sounds thick enough, I think I was using 5-W40 or something at the time.... Something to have your mechanic look at or yourself is there are adjustments on some turbo's that are oil, or oil and water cooled, that can regulate the flow(pressure) of oil, and can be adjusted, to lower the pressure, and thereby reducing blow by in the turbo...

I don't mean to bring up an old thread but I was reading through some threads searching for information and saw a question here I would like to know. In post #2 HardHitter says that after a rebuild there is going to be smoke because the motor is burning off the assembly lube but he didnt know how long it would take. I have never had a rebuild but Im curious to know how long it usually takes to burn this stuff off? What kind of smoke is it? Constant at certain RPM's?

20-30 minutes max, more like 10-15 minutes at idle, is enough to fully burn off the assembly lube and oil used during the rebuild.

HTH,

and make sure your in a well vented area, as it will be enough smoke for people to think your cars is on fire lol.
