Hydraulic Manifold/Distribution Block Issue

78 Model White 2-105 developed hydraulic issue with bucket roll early last week. The dumps under just gravity. There are no leaks I can find. I can roll it up but as soon as I take pressure off the lever it dumps. Lift works fine I thought it was one or both of the roll cylinders so I had both rebuilt last week. With the tractor off or on I can roll the bucket up buy just lifting on the hay spear attached to the bucket. Im thinking Im going to have to pull off the hydraulic manifold.

Other ideas, related drawings, etc are appreciated.

If you have hose couplers, try unhooking the bucket hoses and see if
you can still move the bucket. If you can, you have internal leakage
inside one or both cylinders.
 
With caps on both cylinders hose ports I cannot manually roll the bucket. With the hoses connected I can roll it by hand
