Slide the transmission and the rear end plate out. It is possible to replace the Crankshaft Seal while the engine is still in the car but due to the stiffness of the seal lip, it is highly advisable to perform this with the pan off as well as the seal retainer. And if proceeding, remove the old seal using a screwdriver, put on multi-purpose grease both on the crankshaft journal and lip of the coming seal before installing it properly without hastening the process as it will damage the seal. One of the recommended practices includes lifting the seal retainer and then refilling the rear half of the oil pan. Remove the two rearmost oil pan-to-seal retainer bolts, cut the seal between the oil pan and seal retainer with a putty knife and separate the seal retainer, then any gasket material present should also be cleared, removing as much debris as possible while ensuring body dirt does not drop on the open area of the oil pan; this should be done using clean rags. Place the seal and retainer assembly sandwich between the two wooden boards and apply force on the rear side of the seal so as to pry out the old seal with the force of a screwdriver. Irrigate the new seal into the retainer using a wood block or a section of pipe, approximately next to the size of the OD of the seal. Apply multi-purpose grease to the Crankshaft Seal journal and the lip of the new seal, install another new gasket on the engine block and appropriate RTV sealant to the exposed area of the oil pan flange, especially to the mated surface. Carefully engage the seal and retainer onto the crankshaft as the seal lip will be stiff, more particularly with the aid of a smooth object to get over this part, then install and tighten the retainer bolts to the recommended torque. The residue of the installation is in the opposite order of the removal.
