Withdrawal
Due to the limited area to remove the oil pan, both engine mounts must be disconnected and the front suspension beam lowered.
1. Remove the heater air collection box, refer to Section Removal and installation of the air intake box.
2. Remove the intake air hose from the air collection box, refer to Section Removal and installation of the engine air filter.
3. Models 320d: Remove the engine cover in the oil filter area, refer to Section Connecting and disconnecting the quick coupling.
The operation of lifting and placing the vehicle on stands is dangerous! Therefore, before carrying out the operation, read Section Jacking and towing
4. Raise and place the vehicle on stands. Turn away bolts of fastening and remove a cover of an impellent compartment, address to the Section Removal and installation of the bottom cover of an impellent compartment.
5. Drain the engine oil, refer to Section Changing the engine oil and oil filter.
6. Models 320i, 323i, 328i: Remove the oil drain hose from the oil separator on the oil gauge guide tube. To do this, disconnect the clamp (arrow illustration).
7. Unscrew the guide tube of the level gauge at the holder. Remove the guide tube upwards from the oil pan. In this case, pay attention to the sealing ring.
8. Models 320i, 323i, 328i: Turn away bolts of fastening of the pump of the power steering and suspend on a wire with the attached hoses to the engine, address to the Section Removal and installation of the hydraulic booster pump.
The hoses must be left connected to the pump, otherwise oil will leak out. If the hydraulic system is opened, special cleanliness must be observed, as dirt that has entered the system can lead to failures.
9. Raise the engine with a crane by the front eyes. If a crane is not available, thread the cable through the eyelets on the engine. Pass a pipe of sufficient strength through the cable and support it on two stands.
The BMW-00 0 200 tool shown in the illustration rests on the left and right on the wing supports and is bolted there. There is a similar KLANN fixture for sale, no. KL-0205-3US.
10. Raise the engine with a crane by 5 mm to unload the supports.
11. Models 320i, 323i, 328i: Loosen the engine mounts on the top left and right about 4 turns.
12. Turn away from the underside of the car of a nut from both support of the engine.
13. Disconnect the steering shaft from the steering mechanism and remove the lower steering column from the universal joint (arrows in the illustration).
14. Disconnect the stabilizer to the left and right of the engine beam.
The following operations are described in more detail in Section Removal and installation of a beam of a forward suspension bracket.
- Remove the amplifier of a forward part of the car.
- Turn away bolts of fastening and remove the left and right cross-section suspension arms.
- Support the front suspension beam with a garage lift and support it accordingly. The illustration shows a BMW-31 2 220 support. If the specified support is not available, place a piece of wood to prevent damage to the beam.
- Loosen the beam mounting bolts and lower it as low as possible.
15. Disconnect the oil level sensor connector.
16. Models 320d: Remove the oil level sensor cable and reverse switch from the holders on the oil pan.
17. If there are oil pipelines AT, remove them from the holders at the oil pan.
18. 316i, 318i: Turn away bolts of fastening and remove the holder of fuel pipelines near the pallet crankcase.
19. Turn away bolts of fastening and remove the pallet of a case.
The illustration shows a 316i, 318i engine sump attached to a manual transmission flange. Remove the bolts on the gearbox flange (arrows in the illustration) and on the cylinder block.
20. Lower the oil pan and pull it back out.
Installation
21. Clean the sealing surfaces of the oil pan and cylinder block.
If a new sump is installed on the 316i, 318i, the oil pickup and suction pipe must be moved to the new sump, with a new seal installed.
The suction pipe has self-tapping mounting bolts. Therefore, the new oil pan does not have threads for the mounting bolts. The bolts cut their own threads when screwed in.
22. Models 316i, 318i: Place a new gasket on the oil pan. Fill in the grooves (arrows in the illustration) in the oil pan seals under the connecting planes of the cylinder block at the gear cover and the locking cover with a permanently elastic sealant, e.g "Drei Bond 1209" or "Loctite Ultra Black".
23. Models 320d, 320i, 323i, 328i: Apply to dividing planes (arrows in the illustration) bead of permanently elastic sealing compound on the gear cover and locking cover, e.g "Drei Bond 1209" or "Loctite Ultra Black." The rollers must be 3 mm wide and 2 mm high. Adhere a new crankcase seal using grease. Check the correct position of the gasket.
24. Install the oil pan.
25. Screw in bolts of fastening of the pallet crankcase, while not tightening them. Lightly tighten the bolts first at the manual transmission, then at the engine. Then tighten all bolts to 10 Nm, i.e. lightly again. If the bolts are overtightened, the gasket may be crushed and the seal may be lost.
26. Insert the guide tube for the oil gauge using a new O-ring. Attach the tube to the holder.
27. Models 320i, 323i, 328i: Clamp the oil drain hose from the separator to the level gauge guide tube.
28. If there are oil lines, fix them in holders at the oil pan.
29. Models 316i, 318i: Bolt the holder of the fuel pipes in the area of the oil pan.
30. Models 320d: Attach the oil level sensor cable and the reverse switch to the holders at the oil pan.
31. Dock and fix the oil level sensor connector.
The following operations are described in more detail in Section Removal and installation of a beam of a forward suspension bracket.
- Raise the front suspension beam and secure it with bolts, refer to Section Removal and installation of a beam of a forward suspension bracket.
- Bolt the left and right suspension arms to the engine beam.
- Establish the amplifier of a forward part of the car.
32. Fasten the lower part of the steering column at the ball joint. Tighten the terminal bolt to 20 Nm.
33. Lower the engine, remove the crane. Bolt both engine mounts. Tightening torques are given in the Specifications.
34. Models 320i, 323i, 328i: Install the power steering pump, refer to Section Removal and installation of the hydraulic booster pump.
35. Fill the system with impellent oil, refer to Section Changing the engine oil and oil filter.
36. Reinstall the air collection box, refer to Section Checking the thermal switch.
37. Models 320d: Install the engine cover near the oil filter, refer to Section Connecting and disconnecting the quick coupling.
38. Install the intake air hose on the engine air filter box.
39. Lower the car on wheels.
40. Fasten the stabilizer clamps to the front suspension beam with a torque of 25 Nm. To do this, the car must be in a normal position.
41. Drive the car and check the tightness of the oil pan. Tighten the mounting bolts carefully if necessary.
42. Bolt the bottom cover of the engine compartment, refer to Section Removal and installation of the bottom cover of an impellent compartment.
