Driving on freeway and white smoke came from undercarriage. Pulled over and oil was dripping on exhaust causing smoke. Not overheating. There is a black hose hanging down that is melted. No markings on hose. Hasn’t been leaking oil on driveway. Drives fine.
My car has 999999 miles.
My car has an automatic transmission.
Without actually seeing the hose that is loose i can only speculate it is the PCV valve or breather hose. If you get a mechanic like one from YourMechanic to inspect it then the proper hose can be ordered to replace the melted one.
