How do you properly remove and install rear oil seal in 4.6L V8 engine on Cadillac DeVille?

Using a thin screwdriver or a seal removal tool, carefully remove the Crankshaft Seal from the engine block, ensuring not to damage the crankshaft surface while prying the seal out. Clean the bore in the block and the seal contact surface on the crankshaft, checking for scratches and nicks that could damage the new seal and cause oil leaks; if the crankshaft is damaged, a new or different crankshaft is necessary. Inspect the seal bore for nicks or scratches and carefully smooth it with a fine file if needed, taking care not to nick the crankshaft. A special tool, available at most auto parts stores, is recommended for installing the new seal; lubricate the lips of the seal with clean engine oil and slide it onto the mandrel until the dust lip bottoms squarely against the collar of the tool. If the tool isn't available, work the seal over the crankshaft and tap it into place squarely and evenly with a hammer and large-diameter socket or length of pipe. Align the dowel pin on the tool with the dowel pin hole in the crankshaft and attach the tool by hand-tightening the bolts. Turn the tool handle until the collar bottoms against the case, seating the seal, then loosen the tool handle and remove the bolts and the tool. Check that the seal is installed evenly and at the same depth as the original, with the remainder of the installation being the reverse of removal.
