Trying to change all the fluids and gaskets today, all is going well until I try to take the oil filter off. I try the big graphite nut, the steel strap oil filter wrench,and neither works, I get the biggest pipe wrench I can fine and voila, it mangles the oil filter into a nice greasy piece of origami. Any ideas how I can get this now ruined thing off? I've tried everything I know how, I would love to start the engine up and see if getting it warm might help, but not with a big gash in the filter. thanks.
