2000 Buick LeSabre
After driving the car awhile and when it's fully up to operating temperature on the way home, I'll turn the A/C off and then turn the fan on full blast. This is my routine for drying out the A/C ducts before parking the car in the garage overnight. Well as soon as I switch over to the fan, I get a burning oil smell blowing me in the face. I'm assuming engine oil is getting on the exhaust system somehow. The only thing I can think of is the rear valve cover gasket being the culprit. You guys have any idea what else it could be?
