What color is Porsche smoke?
Smoke that is blue or gray in color is a sign that there is an oil leak. As the oil lands on engine components, it burns and gives the smoke either a blue or gray tint and also a strong odor. Oil can also be leaking into the combustion chamber and burn that way as well.
