How should the crankshaft be cleaned and inspected for damage on Nissan 300ZX?

Clean the crankshaft with solvent and dry it thoroughly, ensuring to clean the oil holes with a stiff brush and flush them with solvent. Check the main and connecting rod bearing journals for uneven wear, scoring, pitting, or cracks, and inspect the remainder of the crankshaft for any cracks and damage. Measure the diameter of the main and connecting rod journals using a micrometer, taking measurements at several places to detect taper and out-of-round conditions, and compare these measurements to the specified outside diameters. By measuring at multiple points around each journal's circumference, determine if the journal is out of round, and take measurements at each end of the journal, near the crank counterweights, to check for taper. If the crankshaft journals are found to be damaged, tapered, out of round, or worn beyond specified limits, it will need to be reground by an automotive machine shop, and ensure to use the correct oversize bearing inserts if the crankshaft is reconditioned.
