Smokin??

Hey guys my car just got a rebuilt engine put into it and it runs good and all but it smokes kinda bad when u give it gas and even after u turn of the car it smokes from the exhaust pipes fro a minute, and it smells kind off bad to my buddy says its proboly just old fluids just burning up from sitting so long but i dont know..... any ideas

probably old fluids. you can wait it out, or have the engine steam cleaned. I'm not sure of the process involved in steaming it, but its also very useful in determining new leaks, or where leaks are coming from.
