I apologize if this question has been answered before. There are 471 pages of threads and I could not think of a good way to put my question in search. If there is another thread I would apreciate someone directing me to it.

When i try to curl my bucket up it will not curl all the way and it goes very slow. AS soon as i put the control to neutral the bucket curls all the way down and just hangs there loose. I do not see any hydraulic leaks. I went to check my fluid level and when i got the dipstick out there was some air came out under pressure.

Sounds as if bucket cylinder piston seal is leaking internally.On subject of air pressure in hyd sump sounds as if sump breather is clogged.

If there are any quick connects between the valve and the bucket cylinders, I would check them out first.

Given the description, I don't think it would be much else. Most cylinders on stuff that I own eventually creep, but in days to weeks, not seconds.
