Hi,
I just bought a used Windstar and went to change the air filter before I went for my emissions test. To my surprise, I found motor oil in the air box. I checked the oil dipstick just for the hell of it and noticed that there was around an extra quart of oil in the engine. I also notice an oil burning smell from time to time and after lots of city driving the idle seams to rev up and down. I was wondering if anyone new what might cause the oil to be in the air box and if that has anything to do with the burning smell and idle issue. There is no smoke coming from the exhaust and the vehicle passed the emissions test with flying colours.
Thanks,
Carl
