    Q:
    Can the rear Crankshaft Seal be replaced without removing the oil pan or crankshaft on 2.2L four cylinder engine on Chevrolet Blazer? Posted by Elling H.
    A:
    The rear crankshaft bearing oil seal can be changed without taking out the oil pan or crankshaft. The first thing you need to do is to remove the transmission. If you have a manual transmission, remove the pressure plate and clutch disc. You'll then take out the flywheel or driveplate. Carefully pry the seal out of the block using a seal removal tool or large screwdriver. However, ensure that you don't scratch or nick the crankshaft in this process. After removing it in this way, clean bore in the block and crankshaft at seal contact surface. Determine whether there are any scratches, nicks on its surface that might damage new seal lip and therefore lead to oil leakage. When crankshaft is damaged, new different crankshaft is required only. Lightly coat both outer edge of a new seal with clean engine oil and the lip of its mouth with engine oil as well. Use J34924 GM tool(if available) and press it into place until it is fully seated with rear facing towards front of engine where necessary, otherwise just carefully work seal lip over end of crankshaft and tap seal into bore until square and seated with hammer and blunt drift when no tool is available. Next step is installation of a flywheel or driveplate as per your choice; on other hand if it's a manual transmission reinstall pressure plate plus clutch disc accordingly after which fix back transmission eventually.
