Just curious, but why two oil pan gaskets? If it is because you keep loosing oil, pretty good chance it is the DoD. Also in the tune you can opt to remove the DoD completely out which you may loose a few miles per gallon, but won't be burning oil. Deal with it is when the DoD activates, it is still oiling the four "inactive" cylinders along with the four firing cylinders. When the DoD is deactivated you now have a cylinder loaded up with oil.
