Alas, the cause of white smoke could come from water in the fuel or antifreeze leaking into the cumbustion chamber or a myriad of other things. IE if you fuel/air mixture is too lean. Im worried about the blueish smoke; that indicates you are burning engine oil and that is not a good thing. You should check the level and composition of both your antifreeze and your engine oil. If the oil is contaminated with antifreeze it will have a milky look and quality to it. If the antifreeze level is down and/or contaminated with oil you may have something like a warped head on your engine. And how do i know this? Same thing happened to me. Of course if the smoke was pure white and not blueish it might be something as simple as a clogged fuel filter which wud cause your engine to run lean and the rpms to oscillate before the engine is starved of fuel. OR it could be water in your fuel. Check out the level of the oil and antifreeze and if either is contaminated. also check and replace your fuel filters and see if there is water in the bowl. and come back to us with the results.
