Darn it ---- still have issues

When motor is off reservoir is about 1/3 full - when I crank the wheels back and forth fluid level rises to the very top of the reservoir - then when I crank the wheels back the other way the fluid drops to about 1/3 again..... all seems fine

HOWEVER - when I start the engine the reservoir empties thus allowing air back into the system.

When shut off the fluid level returns to about 1/3 then when cranking wheels with the engine off the fluid rises all the way back to the top ( essentially overflowing) ....

Is my reservoir to small ?? Something is a miss here
