A little while back i posted about the new Gen II oil pan gaskets. The original oem gasket was composed of a rubber gasket that was attached to a composite base material that could become brittle and fail. The new generation of gasket replaced the composite base with an aluminum base. It may not be a problem, but, the new style has a rubber gasket (attached to the aluminum base) that is a bead approximately 1/8" in width.
The point I tried to make earlier was that the gasket bead seemed way too small to get a good seal unless all is perfect. A hidden defect in the gasket bead could cause a leak. I never had a leak with the old style gasket and I had pulled the pan several times. I just thought it was time and when I pulled the pan this winter I replaced the original gasket. It leaked from day one and I pulled the pan two more times to try and get it to seal.
I end up buying a second new gasket and it sealed the first time I put it on. I kept the leaker and looked at it closely and cannot find a defect, however, it does leak. I sealed the four corners each time the same way with high temp silicone.
