For removal and installation of oil seals, it is recommended to use special tools. To access the front oil seal located in the lower timing chain cover, remove the vibration damper. The procedure for gaining access to the rear oil seal is described below.
1. Remove manual transmission or AT (see chapter Manual gearbox and clutch or automatic transmission).
2. Drain the engine oil (see chapter Vehicle settings and routine maintenance).
3. Remove the flywheel (see Section Removal and installation of a flywheel).
4. Turn out bolts of fastening of the pallet of a case from transmission side (see illustration).
5. Loosen the bolts securing the upper section of the oil pan (see Section Removal and installation of the upper section of the oil pan).
6. Turn out bolts of fastening of a cover of a back epiploon of a cranked shaft.
7. Carefully detach the oil pan gasket from the rear oil seal cover and remove the cover.
After removing the rear oil seal cover, check the condition of the oil pan gasket. If necessary, remove the oil pan and replace the gasket (see Section Removal and installation of the upper section of the oil pan).
8. Starting from 04.1998, a new type of oil seal is used in series and when replacing (without helical coiled spring expander). This oil seal must only be stored with the special bushing. If the gland has been stored without a bushing for more than six months, do not use it.
In the new version, the working lip of the stuffing box is very sensitive, and in no case should it be bent. Do not touch the working edge with your hands.
9. The rear oil seal cover is supplied with the oil seal. If necessary, remove the old oil seal from the cover and press in a new oil seal.
10. Replace the rear oil seal cover gasket. Apply a thin coat of Drei Bond 1209 sealant evenly to the corner joints of the cover plane with the oil sump.
11. Lubricate the seating surface of the crankshaft with oil, put on the crankshaft rear oil seal cover, avoiding distortion, and tighten all the oil seal cover bolts.
12. Further installation is carried out in the reverse order of the dismantling of the components.
