    Q:
    Can the rear main bearing oil seal be replaced without removing the oil pan or crankshaft on 2.2L four cylinder engine on Chevrolet Blazer? Posted by Customer
    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.

    Q:
    How should a new or reground crankshaft and Crankshaft Seal be installed in V8 engine on Chevrolet Caprice? Posted by Customer
    A:
    Do not overlook the bearings for use when a new crankshaft is being installed or when the crankshaft is being reground. First of all, install the rear main bearing oil seal on the top part of the cylinder block seat and on the bottom of the rear main bearing cap, the lips should facing the front of the engine; if the oil seal has two lips the helix should also face the front. For the seal halves use a protector installation tool and lubricate the seal lips with engine oil only. Subsequently, use the main bearings into the cylinder block and the main bearing caps and apply engine oil on the bearing surfaces. Take your time to ease the crankshaft into place in order not to mar the bearing surfaces. In order not to have the sealer obstruct the crankshaft or seal, paint a thin layer of brush on sealer selectively on the block mating surface and the corresponding surface of the bearing cap. Screw in the main bearing caps to the crankshaft and over the cylinder block so that arrow points to the front of the engine. All the attaching bolts of main bearing caps should be tightened to the indicated values but the rear bearing cap should tightened in the range of 10 to 12 ft.lbs initially. From the end of the crankshaft strike by the lead hammer both at the rear and at the front to center the rear bearing, and then re-tighten all bearing cap bolts as required. To determine crankshaft end play push the crankshaft as far forward as you possibly can and use a feeler gauge to determine the clearance between the front of the rear main bearing and the crankshaft thrust surface. Last, tighten the flywheel that will help in rotating the engine when reassembling.
