How should the crankshaft be cleaned and inspected for damage on Pontiac Grand Prix?

Clean the crankshaft with solvent and dry it with compressed air if available. Check the main and connecting rod bearing journals for uneven wear, scoring, pits, and cracks. Rub a penny across each journal several times; if copper rubs off and is embedded in the crankshaft, the journals should be reground. Remove all burrs from the crankshaft oil holes with a stone, file, or scraper to ensure the oil holes are chamfered, preventing sharp edges from gouging or scratching the new bearings. Inspect the rest of the crankshaft for cracks and other damage, and have it magnafluxed to reveal hidden cracks at an automotive machine shop. Measure the diameter of the main and connecting rod journals with a micrometer, comparing the results to the specifications, and check for taper and out-of-round conditions by measuring at several points around each journal's circumference. If the crankshaft journals are damaged, tapered, out-of-round, or worn beyond the specified limits, have the crankshaft reground by an automotive machine shop, ensuring the correct size bearing inserts are used if reconditioned. Examine the oil seal journals at each end of the crankshaft for wear and damage; if grooves, nicks, or scratches are present, the new seal may leak upon reassembly. In some cases, an automotive machine shop may repair the journal by pressing on a thin sleeve, but if repair isn't feasible, a new or different crankshaft should be installed. For a Quad-4 engine, check the oil pump drive gear for wear and damage, and if replacement is necessary, take it to a dealer service department or an automotive machine shop, as the old gear must be drilled and chiseled off while the new gear should be heated in an oven prior to installation. Examine the main and rod bearing inserts.
