Just my two cents worth, it's free and remember you get what you pay for. Sorry to hear about your trouble, and the pox on the factory
for not having at least some suggestions. It's a disgrace on them.
What I'd do:
Open all the identified bleeder valves. I think you've done that already.
Open any other valves too, but try to do one side of the system at a time. Start with the reservoir side
as you are trying to push all the air along ahead of the oil. Try and get a visual concept of what needs
doing and it will all become a piece of cake.
Now the hard part:
Get a trained Tarantula spider, 'cos they have eight eyes and could watch all the bleeder spigots. Otherwise get
Jose and Ramos to watch the bleeder spots and say '"nada'' or to shout "aceite" when oil starts running out without any
bubbles. It should be oil only, no little spits and squirts, just a clean steady flow. Catch the overflow in a clean container
and simply recycle it through. ( I'd filter it first though through some cloth or wadded tissue )
If you are alone, spread some tissue below the bleed points... you may waste some oil but can gauge the amount
that came out. Keep the pump "on pressure" while closing the bleeders. You can also rig up a temporary "gravity feed" system
using a can or a hose and funnel etc. Just raise it up to provide oil pressure. ( You have those things on board, right? If not
you have no business being out there on your
Pump quite slowly and keep checking.
Now In theory at least, of course and off-course, the pipes, T's and all will fill up and overflow. That is where you shut
them closed and continue pumping for the one next up the line to start bubbling and then leaking steadily..
After you have pumped through a pint and still have no gusher going I'd start looking for the overlooked go-zouta that
by now has made a nice big lake on the master cabin bed or another unfortunate location.
You did say the one side emptied 'cos of a bypass flummox but there may possibly be another fault. Hydraulic systems were
not really designed to loose oil, something did likely go wrong somewhere. Perhaps an over-pressure event blew a hose
or a fitting off and it's now become a drain line to no-where. After a coffee mug of fresh fluid you should start seeing some
results, unless there are empty 2ndary reservoirs someplace or empty piston chambers that need refilling first.
Good luck. I'm waiting for FedX to bring in my replacement power steering pump for the car this morning.. a quite similar
problem. Power steering fluid all over and lotsa smoke from the belts. Failure: shaft seal on the pump itself, identified only
AFTER I fixed a suspect hose connection to it.

My system has 8 purge valves, the highest one is at the starboard wheel. On the port wheel is the reservoir .
The system has air because there was a leak on the starboard bypass and the oil reserve got emptied, so now the port wheel does not move unless the bypass is open. I started by filling the reservoir with oil but I'm not sure where to start purging.
Each jack has 2 valves, then there are 2 Ts with a valve each, so that's 6 valves plus another one on the autopilot motor, plus the top valve at the starboard wheel ( 8 valves total)
The jacks are at the lowest point, the Ts and the pilot in the middle.
Thank you for any advise
