Chris-it's a Janome 9000. So far, I've sewed with it for over an hour and no squeak. He used some kind of special lubricant that started with an "L". But basically, he said if it comes back that the part would need replacing...if not replaced it will completely "go" eventually. He couldn't find any rough or weak parts on the presser bar, he had to use 3 different types of oil before this one did the trick, so that doesn't sound very good...I really don't want to lose my buddy:< It's kind of up in the air at this point if it's really fixed or if the squeak will come back.
