How can I temporarily fix the crankshaft or bearings or whatever... on 2001 Toyota Camry

I waited way way way too long to get my oil changed and now my mechanic says I need to replace the engine. I dont have the money for it and would just like to at least replace the bearings in the crankshaft so I can sell it... does anyone know of a better way to fix it so it lasts a little longer?
