Welcome to ZDriver!

Where did you get the motor and turbos? Did you have them checked before installation? Any warranty?

 

Well is it white or blue? White = coolant, blue = oil. Either way, your turbos are suspect.

 

cant say if is blue or white... but i must tell you that when i stop at the traffic lights after a good speeding a cloud of smoke covers the area...i was thinking about worn valve guides... if it was the turbos i think it must blow smoke when accelerate and that is not happening...
