Right oil seal (chain drive cover seal)
1. Remove the crankshaft pulley.
2. Carefully remove the oil seal by prying it out with a large screwdriver, without damaging the oil pump gears and cover.
3. Clean the seal housing and remove all burrs and sharp edges, which can be the main cause of seal failure.
4. Lubricate the working edges of the new seal with a thin layer of consistent grease, carefully put the seal in place so that the lips of the working edges are facing inward, without damaging the edges of the seal. Press the seal with a mandrel until it stops against the flange on the periphery of the seal. The diameter of the mandrel should be such that when pressing in, the mandrel rests against the outer edges of the seal. When pressing in, do not damage the working edges of the seal.
5. Remove any remaining grease, then install the crankshaft pulley.

10. Using your hands, without using any tools, carefully place the working edges of the oil seal on the crankshaft journal to be sealed. Press the oil seal without distortions until the flange on the periphery of the oil seal stops in the annular lug on the crankshaft/cylinder block housing. If necessary, it is permissible to seat the oil seal in place with light blows of a soft-faced hammer.
11. Remove any remaining grease, then install the flywheel (or the leading disk of the torque converter).
