Blue smoke is burning oil, Black is too much fuel or too little air, whitish is too much air or too little fuel, so oil is getting into the combustion chamber somehow is my theory...my 300 has no glows wired, a puff of light blue followed by a small amount of black smoke when accelerating for the first 30 seconds.....not clouds of blue smoke, quite what the suggestion regarding throttle cable relates to is beyond me.......
So either worn bores, worn valve stem seals or worn oil seals in the turbo, or an intercooler with oil in it would be my guess......
