    My Bach valves started hanging after about 6 years of use. I too was using Al Cass. I got a new set of valve springs, cleaned the valves and casing with acetone (watch out if your horn is laquered!) and switched to a synthetic oil La Tromba T2. No more problems.

    If I look at the wear pattern of the valves where I only used Al Cass, I see sub optimal protection. I don't use it any more and have become an advocate of synthetic oils. They just seem to hold up better.

    If your valves are badly worn, they will rub in the casing. as old as your horn is this could be the case. a thicker valve oil will help in the short turn. do you have a local shop that can do a compression test on the horn. can you wiggle the valves in the casing? if they are worn a good pro shop can rebuild them. I'm sure we all can offer suggestions. I've been very happy with the valves I've had rebuilt by Osmun brass.
