I have a very stubborn can-type oil filter that's stuck to the block of my '65 Mustang (I know, not a bimmer in the bimmer forums, tsk tsk). I've tried a strap wrench, a cap wrench and the old 'drive a long screwdriver through the filter as a handle' method, all to no avail (I was admittedly gentle with the last method, for fear of shearing the filter in half and being even more screwed.)

Any sage advice or nuggets of wisdom? Thanks.
