I don't know whats happened in the past life before i bought it. It was wrecked went i got it was not taken care of very well. I wanted a project and i love these cars.My wife reminded me it had straight water in the reservoir tank when i got it. I don't know what else it could be other than head gasket. When i say theirs oil in the antifreeze its a few drops. If you just glanced in it you wouldn't notice. Hope I got to it fast enough.
