Toyota 4Runner Motor 1kz problem

Good morning.
I wanted to know if any of you could help me I have a problem with a 4runner MTORO 1KZ we just changed it to the butt and it turns very well work well for 3 minutes past 3 minutes begins to throw a lot of smoke and feels a great smell of diesel and if it goes out for a while and then it comes to turn on it does the miso work well at the beginning and after 3 min he returns. To review and work very well I don't know if someone has happened to something similar and has an ide of what could be.

thank you

What color is smoke ???

It is true color is important to determine the problem, although I imagine it is black, the clock of the temperature to have both data and tell us.

The gray smoke,

already solved the problem, what I had is that when buying the new butt, it was sent to a rectified workshop to calibrate and settle the valves but made a bad settlement of the valves what I did is that the start and maintain it as 1 hour started and little by little it was removed the problem and in the end when the valves settled.

Thanks for your answers
