My loader is leaking at the plate that has two hex bolts.its where the the handle pushes and raises the valve.my guess it has o rings.what all seals this from leaking and what's inside there.

Your picture is out of focus so hard to see what ypu are talkingvabout. Here is t G e psrts diagram for your valve. Can you circle the area that is leaking?

Would this cause the hydraulic fluid to pour out at a pretty steady stream.leaked a bunch out.
The oring seals the spool to housing clearance where the spool passes through the tank core. If its badly damaged it could leak pretty heavy. Even more so if you have something else wrong and you are pressurizing the tank core.....

I have zero actual experience with that valve but I would think it is supposed to be flat. If it's bent I would be asking myself how and why...
