Remove the crankshaft pulley and vibration damper. Note how the seal is installed, as the new one must be positioned to the same depth and facing the same way. Carefully pry the oil seal out of the cover using a seal puller, ensuring not to scratch, gouge, or distort the area where the seal fits to prevent oil leaks. If replacing the seal with the timing chain cover removed, support the cover on two blocks of wood and drive the seal out from the backside with a hammer and punch, taking care to avoid damaging the area around the seal. Apply clean engine oil or multi-purpose grease to the outer edge of the new seal, then install it in the cover with the lip facing inward and the words on the seal facing outward. Drive the seal into place using a seal driver or a large socket and hammer, ensuring it enters the bore squarely and is seated properly. Check the surface of the damper where the oil seal rides; if it is grooved, a press-on sleeve may be available to renew the sealing surface. Lubricate the seal lips with engine oil and reinstall the vibration damper using a vibration damper installation tool to press it onto the crankshaft. Install the vibration damper-to-crankshaft bolt and tighten it to the specified torque, then install the crankshaft pulley and tighten the bolts to the specified torque. The remainder of the installation follows the reverse order of removal.
