Toyota Repair: toyota smoking., antifreeze coolant, valve seals

Question
My Toyota started smoking blue/white smoke on startup and a bit on pulling away, runs like a dream still, just spent a couple of grand on having 4 new injectors, as this is what my toyota garage said it needed. Just got it back 2 days ago and it is still doing the same thing, now what do I do, any suggestions would be great.
many thanks.

Answer
Blues smoke is usually caused by the engine burning some oil, white smoke/steam is usually caused by antifreeze/coolant getting into the combustion chamber, I would recommend having it tested for a possible blown headgasket and possible oil consumption through either the valve seals or if it has a lot of miles, a piston ring problem. Injectors don't cause this type of smoke/ tailpipe emissions.
