Well mine's immobilised after a fairly comprehensive HGF - hydro-locked No7 with coolant bleeding into adjacent No 5 cyl.
Trying to work up the time and enthusiasm to fix it. On the upside it still runs remarkably well on 6 and it had a complete top overhaul by the professional racing engine builder I bought it from 2 years ago, so it's all pretty clean and should be fairly easy to do . . . (Famous last words).
