a hyd leak under pressure causes heat and maybe a hissing sound. I would use a laser heat temperature gun and point it on all hydraulics untill you find a hot spot. the laser guns are only around $20 and can find hot spots instantly. I use mine on bearings, wheel brakes, rear ends and also in electrical cabinets to find loose wires and hotter breakers. I would guess it's a worn or broken internal seal if you don't have an external leakage anywhere. hope you locate it.
