I own a 2000 Disco II and had to replace the rear ACE lines from the valve block back.While trying to remove one of the corroded old lines,I monkeyed up one of the nylon seals in the valve block.Now I have a small leak around that seal.Does anyone know if these can be replaced?Or will I have to replace the entire valve block?

 

Call your local dealer and talk with the parts people, they are the only ones that can tell you for sure.
