The only problem that I can identify with my '01 Outback is oil dripping on the exhaust manifold and making white smoke. The longer the vehicle runs the thicker the smoke becomes. The engine is not overheating and all the fluid levels are still normal. Do you think it would be safe to drive roughly 100 miles to go to a Subaru dealer or should I go to a small town mechanic to try to determine the problem? I have no idea where the oil is leaking from but I do not know the severity of the problem and whether the vehicle can be trusted to make the voyage to the city.
