Welcome too the Toyota, you most likely wont go back to anything else. I have had very little experience with 3rd gens blowing some smoke. Usually bad rings if its a constant bad smoke while driving and most people live with it till overhaul time which can get pricey.
Also could be a bad valve seal. Expecially if the car smokes a lot on startup and then it goes away. What happens is the valve leaks oil into the cylinder on top of the piston and when you start her up it burns off and goes away. Most people live wiht this also till overhaul time.
