I now follow the advice I read on this forum a year or two ago: use "yellow death" adhesive between the cork gasket and the valve cover (and/or the cork gasket and the oil pan) and no adhesive on the other side. "Yellow death" is, I think, 3M weatherseal adhesive (comes in yellow and black). What you describe is the same principle but different adhesive.
