Well, if there is what you say is in the pan, then you have two options. You can fix it, which would consist of an overhaul plus replacement of all failed hardparts, or you can ride it out until it leaves you stranded. If there is metal debris in the pan (not just sludge on the magnent but actual metal pieces) then something has come apart inside.
