Michelle,
It is quite possible that if your tank was ever layed on its side, the odorant oil could have gone through the gas line.
Here's a true story that relates to your story. Don't try this at home:
There was a guy at a glassworking demo in Seattle who said that he heard that if you lay a tank on its side, you could get more heat out of the flame... so, while an artist was giving a demo, he layed the tank on its side (without the artist knowing). The torch went from having a nice blue flame to being a flame thrower with a solid yellow brushy flame - huge. That, of course, scared the artist. They soon realised what had happened - that this guy had the bright idea to lay the tank over. When it was stood back up, the flame took a while to change back to blue. It then had balls of yellow shooting out, almost like a fountain firework. It never completely cleaned up during the demo, because the oil was still dragging through the propane line.
So, my guess is that your tank was somehow shaken or layed over and the odorant oil went through your line and through your torch. This was no fault of your torch. And, your torch should not be damaged by this.
If you feel that the oil hasn't cleared your line, then perhaps you should get a new line.
