WBSC2 HEPI V2 Leak at Parker Valve

Noticed some fluid in the bottom of the SW SEI Pier at the BS.  Cleaned up the mess in the Pier yesterday and this morning found fresh fluid.  Climbed up to Housing and found the Vertical Actuator Fluid Catch overflowing.  I can see drips coming off the Parker Valve.  Can't tell if it is coming out of the Valve itself or just the Valve/Manifold seal.  It looks like it could be the former.  I'd like to clean up the catch and tighten the valve to manifold screws and see what it looks like in a couple days.

This may require a valve change which would briefly glitch the fluid pressures twice and in between have the BS HEPI uncontrolled for a few hours as we bleed after the valve change.

I cleaned up the Catch Pan and checked the Valve to Manifold screws.  They were plenty tight.  When I look again (Monday, tomorrow?) I'll be pretty confident about from whence the leak comes but I fairly sure now that is is from the Valve itself.
