743 leaking aux valve

[willett]

I built a wood splitter for my 743 and when I run the aux spool something on the bottom side of the aux valve leaks. Aside from obvious o rings and hoses is there anything common that would possibly be leaking? This machine sat for a very long time so I'm assuming that it's probably something simple but this valve looks pretty crappy to pull so I think it's going to wait until spring.

The hose at the bottom of the control block is known to fail with age, it could just be bad seals in the aux segment of the control block too.
