From your routing, the by-pass is open and sending the oil to the upper line. It's leaking is probably related to either the engine having too much internal pressure or air is coming in from the second breather and exiting from the higher original factory one and causing issues with the oil trying to flow inward against it.
Not real sure what the purpose of the alternate oil route would be since I've never seen that on another vehicle so far. If it was providing essential oil, they wouldn't have made it only functional when the valve was in by-pass mode.
Can you open the lines up front and confirm that oil will flow from the oil cooler lines? Or do you have the oil cooler shut off by manual lever if still installed? I don't have the levers on mine so can't turn them off if I wanted to.

Which extra breather are you referring to David? I have the breather in the usual place above the fuel pump and thats it. I do have two pipe elbows on the crankcase as you do.
I have not had any opportunity to look at it today, as we have been watching Olympics...family things. But will check this all out tomorrow.
One thing to bear in mind is that this oil was not pouring out on the 20 mile road run. Maybe the oil cooler has fouled up and is causing a restriction. Although I have blown air through and it pushes oil back out pretty easily.
I really appreciate ALL your help and ideas. I will report back asap when I have got to look at it in more detail.
ps David, no taps on the later oil coolers to shut off supply.
