That said the yellow oil looking stuff appears to be coming out of the water hose from when it overheated... I'd say it's definitely not water condensation, however, the car has been smoking white smoke, and the nasty burning oil smell has been coming from the engine randomly for some time now. I assumed it was a common oil leak. The oil mixed with water is new. Is it possible for the oil separator to mix oil and antifreeze together?
