You could still have leaks across either one or more of the valve spools, acrosss one or more of the cylinders pistons, or both.
The fact that the loader only drifts down a little and then stays in position when the hoses are disconnected from the tractor only means that the incompressible hydraulic fluid trapped in the loader has run out of places to flow and the pressure has equalized across all the valves and across both sides of all the cylinders.
A good example of this is taught in most beginning hydraulics classes. 1. Connect both ends of a cylinder together with a hose with a pressure gauge. 2. with the rod end up, place a weight on the rod. 3. the pressure on both sides of the piston will increase and equalize at a rather high pressure equal to the weight over only the cylinder rod. The bore of the cylinder no longer has any effect, only the weight and the rod size matter.
