T5 105 slow hydraulics

[Slowcow]

We've a 2015 T5 105 coming up 7000hrs.
Hydraulics have got pretty slow, changed all the filters fresh oil etc. Most noticeable using the loader and gets worse as it warms up, I checked the oil after about a hour and it's very bubbly on the dipstick.
Before I hunt through the manual and scrawl underneath , anyone else had similar? Is the a gauze on the pickup or a joint in the oil feed pipe that can draw air?
Other than that next is a new pump
Cheers

Almost certainly need a new pump,7000 hrs loader work is a good life for a hydraulic pump.
