ARB air locker pumping oil

I have just had an ARB air locker installed and it is pumping oil up the air line and blowing it out the solenoid. I have had it taken out by a different shop and had the o rings and part the o rings sit on replaced but it still blew a t spoon on oil out solenoid in 1 day. Is this normal. What do you reckon could be wrong.

check your vent tube, it might be blocked.
