Water from top of Euphonium 4th Valve ... HELP.

Hi all.

I recently purchased a 1989 Besson Sovereign Euphonium. It's in great condition, but the 4th valve constantly leaks water from the top (around the stem) whenever I lay down the instrument on it's side. I know it has a direct correlation to needing to empty the main water key but I've never seen water leak like this before - it's literally constant. This is also causing the felt a the top of the valve to be saturated so the valve clangs like crazy when released.

Could it be that I need to use thicker valve oil, or is it something simple (or far more sinister) that I've just not thought of.

Any advice appreciated.
