Jeff,
Take some photos of what is going on with the seals, any out of adjustment visual that you can see, slide wise (spacing's etc), as well as the leak details. Send the photos to BCS or Alliance via Email, especially if you have a contact that you have used at either place in the past. If you call BCS or Alliance and say you are willing to pay for their diagnostics, recommendation, and the parts that they would have you get changed it would seem like that is at least an informed way to proceed. There is hardly anything these places have not seen in the past. You can say no guarantees just guidance. If their input has many possibilities as to root cause and vague directions as to the likely fix then you would have a decision to make on how you want to proceed. It may be worth a trip at some point.
If it turns out that your symptoms provide a clear direction then I would also mention the places you will be near and see if they have a shop that they would recommend. The Foretravel folks equipped with some input/parts from BCS or Alliance would probably be hard to beat if they would do the work. Not sure if this will help but it is a possible path.
Later Ed
