Using the HD one from Geno's. Use the OEM black/Rubber gasket and a light coating of Permetex's "The Right Stuff" on both sides. 40 Ft Lbs torque.
It can't really be put on dry, as even after 24 hours of drain time, it still dips. Would a different gasket do the trick?
I had the same problems with that one. went back to stock for one oil change and then to the ez change plug from genos, no problems in about 70K miles.
