If i leave the car ideling for a while while im not in it...i can smell oil trough my vents when i reenter the car..i dont know if it is oil but kinda smells like it...then when i start driving away the smell goes away....air smells normal trough vents again...do i maybe have a oil leake somewhere? i mean my car is parked in the garage all the time and the car is not leaving any oil spots anywhere...Any help would be appreciated..

 

This is not great but it is normal. you are getting oil mist that is probably from the crank case ventilation system on initial start up nothing to be too worried about. look at your cam tensioners they car weep at night and leak small oil drops on the exhaust as well
