Remove the transmission and all other components necessary, such as the clutch and pressure plate, to access the oil seal in the back of the engine. Next, remove the
Flywheel. Use a small punch to create two holes on opposite sides of the seal and install small sheet metal screws in these holes. Pry on the screws with two large screwdrivers until the seal is removed from the engine, taking care to place small blocks of wood against the block to provide a fulcrum point for prying, while avoiding any scratches or damage to the crankshaft oil seal surface. Apply a thin film of engine oil to the outer edge of the new seal, the seal bore in the block, and the seal lips. Position the seal on a special tool, available at most auto parts stores, and then place the tool and seal at the rear of the engine, installing the seal with the spring side toward the engine and alternating the tightening of the bolts to seat the seal in the block. If a special seal installer is not available, work the seal into place and gently tap it into the bore with a soft-face hammer, using the drive end of a socket extension or another blunt, smooth object to ease the lip of the seal over the end of the crankshaft. The remainder of the installation follows the reverse of the removal procedure.
