Narrative:

We were not boarded. We started smelling a fumes smell; getting stronger. We looked back in the cabin and it was very thick with smoke/fumes. We contacted maintenance and they come out and did some trouble shooting. It was apparently the bleed valve for the APU leaking oil. Maintenance took the plane out of service. We were in the cockpit quite some time trying to figure out what to do. I did not think anything of it at the time; but some months later I starting getting a neurological disorder called bulbar palsy affecting my speech. That was the only event that happened in those months. APU leaking oil into the air conditioning manifold. Be every aware of smoke and fumes and remove yourself immediately.
