Oliver 1365 with 1510 loader problems

[Ficks from Indiana]

I have an Oliver 1365 with a 1510 loader that is giving me fits. The loader hydraulic pump is putting oil back into the main tractor system. I figure it needs a seal of some sort but can not find one nor anyone to work on it. Need suggestions.
I m having continual problems with the 3 point lifting, now this. I m about to give up on the old girl.
Thanks in advance.

The 3pt problem, does it get worse as the oil warms up? Mine did. It was the pump on the right side of the engine. I put a new one
on and it fixed the problem. Less that two hundred dollars when I bought mine in 2017. I got it from Rick's Ag Parts.

The loader pump. you're probably right, a seal. All I can suggest is a good hydraulic shop.
