this one is new to me,i jumped in the car this morning to take my kid to school and after dropping him off i saw a puff of white smoke behind my car ,car runs fine like normal the temp guage was at normal temp.i pull over and look and everyting is fine so i continue home and then it started to run hot,there is no water in the oil and no leaks under or around the car. but the coolant is going somewhere.i dont think its a head gasket,is it possible for a intake manifold gasket to do this? this is odd...any ideas?
