 REMOVAL

1. Uncover air intake, address to the Section Removal and installation of a drive of a screen wiper/cover.
2. Disconnect a hose of the vacuum amplifier of a brake from the inlet pipeline, instead of from the amplifier. For removal of a hose the application of some effort is demanded.

3. Uncover a jellied branch pipe of a fuel tank. Unscrew a screw-driver (shooters on an accompanying illustration) small covers and unscrew the screws which were under them. Remove two plastic facings.

4. Rasstykuyte shtekerny connections of the sensor of oxygen. Rasstykuyte tip of the electromagnetic VANOS valve. Address to an accompanying illustration.

5. Remove a shtekerny level and take her aside.

6. Uncover at the inlet pipeline. Unscrew a positive reference point (1) and compress two clips (arrows on an accompanying illustration). Disconnect a socle.

7. Remove a ventilation branch pipe in the top part of the block of cylinders. Address to an accompanying illustration.

 

Do not smoke. There is a danger of ignition! Wipe following fuel a rag. Disconnect at first the pipeline of giving (1) (from the filter), then the pipeline of return of fuel (2) at the distributive highway. For this purpose open collars. At assembly it is necessary to replace collars.

At some models the pipeline of giving is attached directly to the distributive highway. At assembly it is necessary to replace a sealing ring on new and to grease with vaseline. There is a fastening of fuel hoses in the form of tightening brackets. In this case the BMW 16 1 050 tool is necessary for removal of brackets. Before installation check a sealing ring. In the presence of damages replace it, address to the Section Removal and installation of injectors.

8. Disconnect a butterfly valve branch pipe, address to the Section Removal and installation of a branch pipe of a butterfly valve.

Do not disconnect a drive of gas and hoses of cooling liquid.

10. Unscrew directing pipe of the index of level.

11. Unscrew bolts of fastening and remove a support of the inlet pipeline and a square of a hose of cooling liquid of the inlet pipeline. Address to an accompanying illustration.

12. Rasstykuyte shtekerny connection (1) at the valve of ventilation of a fuel tank. Take out the valve upward from the holder. Press a collar (2) and disconnect a hose. Rasstykuyte shtekerny connection of the sensor of temperature of soaked-up air and the idling valve at the inlet pipeline. Address to an accompanying illustration.

13. Unscrew bolts of fastening and remove the inlet pipeline from a head of cylinders.

Watch that any subjects did not get to inlet canals. It can lead to heavy damages of the engine.


 INSTALLATION

1. Establish the inlet pipeline on a head of cylinders and evenly cross-wise tighten bolts of its fastening. Before installation it is necessary to check all sealing rings (arrows on an accompanying illustration). In the presence of damages replace rings.

2. Fix a support of the inlet pipeline.
3. Join shtekerny connections of the sensor of temperature of soaked-up air and the valve of adjustment of idling.
4. Insert the valve of ventilation of a fuel tank and put on a hose.
5. Fix a socle of a positive reference point on the inlet pipeline and screw a shestigrannik. Fix a cover.
6. Fix on the inlet pipeline directing pipe of the index of level of oil.
7. Put on directing pipe of the index of level a hose of return of oil, fix it a collar.
8. Establish a butterfly valve branch pipe, address to the Section Removal and installation of a branch pipe of a butterfly valve.
9. Put on the distributive highway hoses of giving and fuel return. Establish new sealing rings and collars, address to the subsection "Removal".
10. Fix the ventilation pipeline in the lower part of the block of cylinders.
11. Join shtekerny connections of the sensor of oxygen and the electromagnetic VANOS valve.
12. Establish a shtekerny level of valves of injection.
13. Fix a vacuum hose of the amplifier of a brake on the inlet pipeline.
