... check the larger O-ring to see if it is pinched, deformed, or broken; look for debris in the groove, which would allow oil to slip past it.  Make sure to wipe the engine block clean of debris...

Also check the thickness of the o-ring and make sure it has enough cross section to actually seal, should be contacting both surfaces before you tighten it down.
 I bought an aftermarket filter once that the o-ring was thinner, wound up having to re-use the one I had taken off.
