how do you have your loader hyds plumbed? from an under seat add on spool valve that sets on the hyds cover Blank off area? ASC valve or?

I put some picture to answer to your question but its look like the hydraulic bypass I have disconnect the front end putting a union between pressure line and the return line of my joystick and my 3 point still do the same (3 point lift alone and stock in up position) , I also try to just cap the to line for my joystick feed and return and I have no more hyd pressure to operate the 3 point so now I'm think the problem is related to the 3 point hydraulic system but I'm not sure what I should start to inspect ? the sandwich plate for a busted o ring or find a defective check valve?

Ok, so are you using a power beyond plate and pb capable valve?

If yes, and its plumbed correctly, its possible that your unloading valve is stuck in the lift position.

Where i can find the unloading valve?

it's located on/in the monolithic cyl that is bolted under the hydraulic cover. You actually will need to make a puller to get to it, if it is what is sticking ( in the unload position ).

If your loader hyds work, but not the 3pt, that's where I would investigate.
