Smoke on hot start?
 

Hello. As title says, I get a bit of smoke on hot start only. Not sure the color but it doesn't smell sweet, so I'm thinking oil. This only occurs after I warm it up and drive it a bit then shut it off and turn it back on. It doesn't happen if I warm it up at idle then shut it off and turn it back on. Only when I drive it. The smoke does go away after revving a bit or driving. Any ideas? Trying to sell the car so I just want to know what's wrong with it

Do you have oil in the intake? That's a common explanation for a bit of extra oil making it into the combustion cycle
