well i stripped it all down yesterday and cleaned out the check valves, didnt seem to be too much issue to the eye, but i was thourough anyway, the oil which came out the hose though and the oil which remained in the dumps etc was very black though? ive topped the system back up, ran it a few time and left it to see what happens now, ive measure all 4 corners on the arches to floor and will measure again tomorrow to see if it has dropped (did it last night and the front was ok, the rear dropped about 2" but i was assumong this may because i'd split the system and there was air in the air, see what happens inthe morning
