Here recently I have been noticing, when I crank my 01 Nissan Maxima, there is a cloud of white smoke and it flows the whole time the car is on, running or stopped. The smoke is grey to black when revving engine. There is also a spray paint smell and a kind of sweet smell, thats the only way I know to describe it. I have heard this could be bad fuel or could be a blown head gasket. I had a Mitsubishi Eclipse that did the same thing and it was a blown head gasket. Both of these cars were used, so Im starting to think I got screwed. I knew about the Eclipse. I resold it as needing new motor. I dont know what Im going to do about the Maxi, if this is the problem, because of the year, I wouldnt ecpect the car to have this type of problem already. If so, sounds like someone was rough on it. Thank you in advance for your feedback!
