Caution! Do not apply too much sealant, and work especially carefully in the area of the oil channels. The parts must be assembled within 30 minutes after applying the sealant. After this time, the sealant must be removed and reapplied.
Removal
1 - bolt, 50 Nm; 2 - mounting plate; 3 - gasket, always replace; 4 - nut, 45 Nm; 5 - bolt, 50 Nm; 6 - exhaust pipe; 7 - nut, 90 Nm; 8 - gasket, always replace; 9 - stiffening element (On models with an aluminum oil pan, it is built into the pan.); 10 - bolts 50 Nm; 11 - Gasket, always replace; 12 - oil pan; 13 - bolt, 10 Nm; 14 - oil drain plug, 40 Nm; 15 - gasket, always replace; 16 - mesh filter; 17 - bearing support; 18 - bolt, 10 Nm; 19 - bolt, 20 Nm; 20 - Gasket, always replace
1. Disconnect the ground cable from the battery.
Warning! This will erase the engine fault memory or the radio security code. Before disconnecting the battery, read the instructions in Section Removal and installation the battery.
2. Raise the car.
3. Drain the engine oil.
4. Unscrew the exhaust pipe, lower the exhaust system and tie it with wire, see Section Removal and installation the generator.
5. B3, B6 (SOHC) since 9/89: Unscrew the stiffener.
6. Unscrew the bolts and nuts securing the oil pan.
7. Steel pallet: To press the tray, place a screwdriver between the support bracket and the tray.
Caution! Do not insert a screwdriver between the bearing support and the cylinder block. Also, when removing the pan, make sure that the sealing surfaces of the pan and cylinder block are not damaged.
8. Aluminum tray: Insert a screwdriver into the indicated place between the oil pan and the cylinder block.
Caution! The screwdriver must not be installed in any other place, otherwise the sealing surfaces of the oil pan and cylinder block will be damaged.
9. Remove the oil pan.
10. If present, unscrew the bearing support and remove it.
Installation
1. Carefully remove the old seal from the sealing surfaces of the oil pan, bearing support and cylinder block using a triangular scraper and a razor blade.
2. Thoroughly wipe the cylinder block, crankcase and oil pump. Otherwise, the seal may be damaged by leaking oil.
3. Wipe the sealing surfaces on the oil pan, bearing support and cylinder block with a grease solvent and dry them. Alcohol or acetone can be used as a cleaner.
Attention! Do not use cleaners that corrode varnish surfaces.
4. Apply silicone-based sealant to the shaded areas (for example, DOW CORNING Q3 - 7057).
5. Apply silicone-based sealant (for example, DOW CORNING Q3 - 7057).
6. Install the bearing support and tighten it with force 20 Nm.
7. Apply silicone-based sealant (for example, DOW CORNING Q3 - 7057) on the gaskets and install the gaskets.

Caution! The tabs on the gaskets must face outward, the ends must fit cleanly.
8. Apply silicone-based sealant (for example, DOW CORNING Q3 -7057).
Steel pallet
1. Install the tray and screw it evenly with force 10 Nm.
2. Install the stiffener and tighten the mounting bolts with force 50 Nm.
3. Aluminum tray: Install the pan and tighten the bolts "A" evenly with force 10 Nm, bolts "B" with force 50 Nm.
4. Install the exhaust pipe.
5. Lower the vehicle.
6. Fill with engine oil.
7. Connect the battery ground cable.
8. If available, set the time on the clock and set the security code for the radio receiver.
9. Perform a test drive, check the oil level and the tightness of the oil pan, and possibly carefully tighten the bolts.
