If the loader is a McCormick #30 or #31, the cylinders are designed so as to have a reservoir at the front end of the cylinders. The reservoirs are there to supply needed hydraulic oil to the belly pump, because the belly pump does NOT have the capacity needed to supply ENOUGH fluid to fully raise the loader.

As the loader is raised, the fluid in the cylinder reservoir is pushed back into the belly pump reservoir, thus providing sufficient fluid to fully extend the cylinders.
Remove those air vent plugs and replace them with hydraulic hoses.

The other end of those hoses, both of them, then need to be connected with a TEE pipe fitting, and that TEE fitting can then be fitted to the belly pump fill pipe, using a pipe union fitting. The union fitting is needed to provide a way to fill the belly pump when necessary.

There is NOTHING wrong with your cylinders. They are doing EXACTLY what they were designed to do.

I finally found an ID number on them. It says on the under side of the arm an IHC logo stamped in the arm with the numbers 450 657 R2 I googled this number 7 ways from Sunday with IHC int etc with no hits that meant anything so I can't positively ID it.

I believe Rusty is correct in that the upper cylinder volume will supply extra fluid to assure full travel. I believe he is incorrect in indicating that the cylinders are working as designed. They are leaking, or oil would not get to the top of the cylinder as you describe.
I also believe the best place to route the hoses back to the reservoir is in the drain plug at the bottom of the reservoir. A short pipe nipple, and a cross fitting at that spot will allow draining the system, as well as attaching two hoses for the return.
As I noted, the problem for using the loader would be made to go away, but the piston seals in the cylinder are still leaking. Jim

The method I described for routing the hoses back to the reservoir was taken directly from the McCormick #31 owners manual. However, the part number given by the original poster is too new for a #31 loader, so it might just be that the loader he has is actually set-up for 2-way hydraulics, which his H does not have, and then installing those vent plugs in place of hoses IS correct, and yes, the cylinders need to be rebuilt.

Thanks, I'm looking into it tomorrow.
