Im haveing a problem when i sit at a light and take off from the light to make only left turns is only time it does this in my 94 explorer it puts out a big cloud of blue smoke and it has some clattering coming from the engine it only puffs for a second and the smoke and clattering stop i checked a whole bunch of things and here is what i found the water is fresh green looking. The motor oil which i changed like 400 miles ago is like a quart and a half high and i checked it when i changed it and it was fine and i checked the trans fluid and it isnt on the dip stick at all. what do you all think the problem might be the motor oil has a wierd smell but im not used to watercooled cars any more i havent worked on a water cooled front engine car in a long time im used to burnt up nasty oil that i dont eaven know what is right and wrong any more can some one maybe shed some light on this for me any help would be great
