Remember that foundry sand grains wedge against each other to form sort of a porous solid--that's what makes it into a mold. Do you know how much excess oil you put in? I suggest you buy some more dry sand, and blend it with the stuff you have to produce a usable proportion. If that would be too big a batch, just use part of your wet sand at a time, until you have eventually worked it down.
Try wicking out the oil - paper towel would absorb nicely.
Have you added rosin ? It is used to flow around and make smooth sides. It will absorb a good deal as it 'lubes' up.
