I have a Scale and Engineering hydraulic pressbrake.
When I use it the oil foams/aerates very quickly.
I don’t think this is a new problem as, when I bought it, it had a fair bit of oil around the hydraulic bay, but I thought this was just an accumulation from years of use.
I cleaned it up and added oil to the full level.
Next time I used it I found that it was overflowing through the breather after only about 10 minutes use.
The oil is an off white colour and clearly has small bubbles of air in it. This settles out and reverts to normal looking oil over night.
The only things I can think of are contaminated oil, or a leak in the hydraulic circuit spraying into the oil in the tank.
Has any one got any suggestions.
