There is no isolated mono valve on the evil servo system.

The large black box, in the engine compartment contains the plumbers nightmare.

This box has water valving, electrical switching, and vacuum switching.

It is famous for developing cracks/leaks inside the box = soaking electrical and vacuum with hot liquid or STEAM antifreeze = more damage.

There is a digital replacement option, basically the same price as a rebuilt Servo, but it has better durability/fewer problems.

If you plan to fully learn how it functions, I hope you have at least a few weeks free time for reading.

I've located a nice dash pad a well, so it looks like the weekend I choose to do this will be time well spent.
