dude! your crank bearings are probly shot and the races are spinning in the cases!!! it might be too late to save it....you HAVE to split the cases and check it out or it will seized, blow up, or throw a rod or all of the above....when you try to pick the pieces up with a magnet if they can be picked up that isnt too bad, you might just need to rebuild your crank and put new main bearings in, if you cant pick the pieces up you more than likely need new case halves....idk, my 2c.
