engine issues

I have a 98 Millenia there is alot of white smoke coming out of exhaust after it has been idling or as soon as it starts up but when I drive around for a bit its sortof gone and there is oil smell along with smoke and other then that it drives fine, can any one help dose anyone know what it could be?

I've heard of that problem, and it may be because of a bad supercharger... you may want to visit mazdaworld.org forums and ask your questions...
