my car doesnt usually smoke. but if it sits for a few hours it will sometimes. i got to school at 745 and get out @330 and it will smoke a lot. but only for a min. if the car is warm it never smokes. its also a remanufactured engine that got done about 10k miles ago. what is my problem here. is it running to rich?how do i fix this.i know its not oil.

 

what color is the smoke ?

 

they do that b/c the oil injectors let a little oil seep into the combustion chamber while its sitting. only normal. u need to worry when it smokes as u go past 5k rpm... that means bad oil seals...
