Completely disassemble the engine, thoroughly clean the block and all components. If the cylinders show signs of wear (ANY measurable taper) bore the cylinders and replace the pistons. Recondition the rods! If the crankshaft has been damaged ALL OF the rods must be either replaced or reconditioned. Replace all of the rod and main bearings. Inspect the camshaft and lifters for damage or wear and replace if necessary. The prudent mechanic replaces ALL even if only one shows signs of wear. Also, the prudent mechanic always reconditions the head every time the engine is apart. Reassemble the engine using new gaskets, oil pump and timing chain/gear as necessary. Never plan on an engine teardown that will only replace a single component, especially the crankshaft. Typically an engine suffers a great amount of damage when a major component, like the crankshaft, is damaged. If there is ANY indication of heating outside of the normal range, you may have slighly warped the block and you'll need to "align bore" it for the new crankshaft. This is not a good place to plan on an inexpensive repair.
