Remove the engine.
Mount the engine on an engine stand with the engine upright. Remove the oil pan and crankshaft oil windage baffle.
CAUTION: Mounting the engine upside down on the engine stand before removing the oil pan may cause sludge to drop into the cylinders and onto the camshaft and valve tappets causing rapid wear when the engine is restarted.
Rotate the engine upside down and remove the oil pump and rear main bearing cap and wedge seal.
Remove and discard the crankshaft rear main seal.
CAUTION: Prevent engine assembly contamination. Always use necessary precautions to prevent old sealer or gasket material from falling into the engine.
Thoroughly clean all the oil and the old sealer from the oil pan taking special care to remove all the old sealer from the oil pan gasket groove in the oil pan. Thoroughly clean the oil pan.
Thoroughly clean all the old sealer from the rear main bearing cap using a scraper and wire wheel. The original sealer used during production assembly becomes extremely hard after it has cured. It is extremely important that all old sealer is removed from all joining faces and grooves.
Thoroughly clean all oil and old sealer from the cylinder block oil pan sealing area and the rear main bearing cap joint area.
Thoroughly clean all oil and old sealer from the wedge seal sealing area at the rear main bearing cap and the oil pan gasket groove.
NOTE: Preferably use a new wedge seal.
After all parts have been thoroughly cleaned and washed, it is necessary and extremely important that they be wiped down with Extra Strength Spot and Stain Remover B7A-19521-AA (ESR-M5B197-A) or denatured alcohol.
Thoroughly clean the transmission bell-housing area and the rear of the cylinder block. Oil removal should be verified with an ultraviolet lamp ("black light").
