Hello, The problem is either the resolver seals in the loader valve or the inlet priority valve of the inlet section.Either way, the best thing to do is to reseal the whole valve.If you do not have time to reseal the whole valve, start with replacing the resolver check valves.You have one primary and one secondary check valve in each valve section and one secondary resolver in the inlet section.The secondary resolvers are access through holes in the frame behind the right rear wheel.The primary resolver check valve are under the bottom caps of each spool. These are harder to access and should be ok unless you are experiencing cylinder drifting on the loader.
