I did not do a pressure test. The spool had no seals on it per se. There were just blue plastic cup seals on either end pressed into the directional valve. Strange to me was that there was no pocket in the valve body to sit in. The seal was free to travel in the valve assembly only being captured by bolting up the various washers and springs. I am now wondering id the cup seal could have slid in too far and is now opening one of the ports. Odd that the valve body had no way to restrain the cup seal. I guess I will be taking it apart again.
