My trucks been puffing out white/blue smoke when i take off at stoplights, and when the motor is still cold it will haze out. I figured it was a bad turbo seal, so this weekend i tore down the turbo and sure enough it was leaking oil. I cleaned it all up, replaced all the seals and bushings and what not, and put it back on the truck. Its now blowing even more white smoke on take offs, and it has a real light haze when it sits there and idles. I thought it might be a weak injector but the truck starts cold with no struggle like you usually would have with a couple weak injectors. Its studded, deleted, and sct tuned. any ideas on what it could be? thanks!
