That control valve is shot, leaking from the body. I'm pretty sure it was always set up this way other than the 2 ports I have plugged that ran to the lift cylinder for the snow blade. I pulled it apart and cleaned it up with new orings but the spool was badly corroded and pitted. I think maybe this allowed the fluid to push past the lands and cause the leaking. Is it possible that the pitting on the spool is allowing the valve to flow both ways and fight itself? It does make sense to me now that I can find the pressure side of the pb plate and plumb it back to the tank. I'm still not understanding how the valve works when plumbed up in its current configuration. If I were to buy a new control valve and add the additional power beyond plug, how does it function without plumbing a hose back to the tank.
