That’s way too much. Has to have air in the line or someone replaced the oil with water. Close the ball valve and load the car. If it still compresses...

Back out the low pressure adjuster, disconnect the up slow valve coil, run the car up, turn it in til it he car moves then out til it stops. Then out ...
