what color smoke? blue white?
what motor and what have you done to it?
If it is still running right I would say you didn't get a gasket setup correctly or maybe you didn't setup the rings off set from each other... But really had to say with out more info.

Hopefully it wasn't synthetic or the rings breakin won't occur.

Love that TOYOTA
What you need to do first is get your exhaust manifold/header on tight. That truck sounds like ass dude.

By "oil in it" do you mean in the oil pan for normal use, or that you put oil in the cylinders because it was sitting in your garage? If you put oil in the cylinders because it was sitting, then it burning off is normal.

Ok, in the pan. Just making sure you didnt coat the cylinders or anything like that.
Did you seat the rings according to the manufacturers recommendations? I know when I did mine, I had to do some kinda accelerate/decelerate crap to seat them.
I heard an old trick about blocking off the PCV system and supposedly that will build up pressure to seat the rings, but I have never tried it. Only heard of it from an old mechanic.
Also, are you sure you got the rings stacked right with the gaps all going the right directions?

What Exactly have you had done to the motor ? And how did you break it in?
I would check the plugs and do a leakdown test to determine if the rings are the culprit first.
Too much crankcase pressure can push oil past the rings if the PCV is not functioning properly.
Was the head rebuilt also?
