I just bought a 91 Harley Davidson FLTC Ultra. The engine is pushing oil out the vent tube when I tried to start the engine. Was told by the person I bought it from that it would do that when it sat for long periods but was it had been running it wouldn't do it anymore. Any help would be awsome.

Sounds like oil is making its way past the valves and blowing out the vent tube. It may help if you can keep the bike vertical. Best solution is an engine rebuild, including piston rings and valves.
