Could it be possible that I have the centre valve that puts fluid into the ports located incorrectly ? . My pressure gauge is off the “p” port .

That's why you only read 30-40psi. The P port is the pressure Input to the valve. Teeing on that port will only have "Return" pressure until the valve is activated to send pressure to something through one of the Output ports. That something must Also be locked, blocked or at full extension to test pressure.

You have to "dead-head" a port to test pressure.

So my 3 point hitch is working under load . Could this be something stuck with the flow priority valve ? I need to read more about the oil passages .

When lifting a load on 3 point what pressure do you see on gauge you have plumbed into the “P” port of loader valve?

For whatever reason my draft link at the bottom can be seen dripping slow drips of hydraulic oil. Also I have this icon on my dash (unsure why ) . From the back , the switches allow me to lower and raise the 3 point hitch . Still no loader valve . Taking the timing to de-grease everything. It is a slow process . Stuck or failing valve somewhere ??
