Right oil seal (from the pulley side)
1. Remove the crankshaft pulley as described in Chapter 7, paragraphs 4 and 5.
2. Carefully pry the old oil seal out of the timing chain cover using a suitable flat-head screwdriver, being careful not to damage the cover or the crankshaft (see illustration). Alternatively, punch or drill two small holes in the seal, then insert self-tapping screws and pry the seal out with pliers.
3. Clean the oil seal housing and use sandpaper to remove any burrs or uneven areas on the crankshaft to avoid damaging the new oil seal during installation.
4. Lubricate the sealing lips of the new oil seal with clean engine oil and press it into place until its outer edge is flush with the surface of the timing chain cover. If necessary, the seal can be driven in using a tubular drift or socket, which should rest on the hard outer edge of the seal (see illustration). Please note that the sealing edges must face inward.
5. Wipe off excess oil, then install the crankshaft pulley as described in Chapter 7, paragraphs 23 and 24.

6. Remove the flywheel as described in Chapter 12.
7. Carefully punch or drill two small holes in the seal, then screw in the self-tapping screws and remove the seal with pliers (see illustration).
8. Clean the oil seal housing and use sandpaper to remove any burrs or uneven areas on the crankshaft to avoid damaging the new oil seal during installation.
9. Lubricate the sealing lips of the new oil seal and the crankshaft belt with clean engine oil, then install the oil seal into the cylinder block/crankcase, with the sealing lip facing inward.
10. Wipe off excess oil, then install the flywheel as described in Chapter 12.
