Removing oil separator

Note: Cover engine openings (e.g. intake openings, crankcase, oil lines, open reservoirs etc.) cover with a cloth to avoid dirt and foreign bodies falling in.

Note: The air-conditioning lines on the compressor do not have to be disconnected in order to remove engine/transmission unit.

1. Detach air-conditioning compressor without disconnecting the air-conditioning lines.





2. Disconnect ground connector from intake distributor side 4-6-arrow-.





3. Pull the engine compartment temperature sensor out of the intake distributor 4-6 together with the rubber sleeve -1 - and unscrew the rear fastening screws-2- of the air-conditioning compressor.





4. Unscrew the front fastening screw -arrow- of the air-conditioning compressor. Due to the restricted accessibility, the use of a 3/8" extension, 16' movable NR.15 with a long Torx E10 socket wrench is recommended. To lift out the air-conditioning compressor, the screw must be pulled upwards and held in position.
5. Lift out the air-conditioning compressor with the leads connected and lay to one side on a protective support. Secure additionally with a tie-wrap.





6. Remove distributor pipe. To do this, remove the fastening nut M6 of the throttle body from the rubber mount of the servo pump -2-.
7. Release cable plug on throttle body, and pull out and release cable -1 -.
8. Release crankcase venting pipe connection from distributor pipe and remove -3-.





9. Loosen the four screw-type hose clamps on the rubber sleeves to the side intake distributors and push the rubber sleeves onto the distributor pipe. Remove distributor pipe together with mounted throttle body. Remove distributor pipe from the engine compartment.





10. Release tuning pipe. To do this, mark the installation position of the tuning pipe and loosen screw-type hose clamps -arrows-.





11. Remove both side fastening screws -arrows-.





12. Carefully turn the oil separator and pull it out of the bore. Check sealing rings and replace if necessary -arrow-.





13. Remove connections to the oil separator . For this purpose, place a cloth underneath as coolant emerges from the bottom vent line. Press and remove the connections -arrows-. Remove oil separator from the engine compartment.

Installing oil separator





1. Check seals of oil separator and replace if necessary. Place oil separator in the installation position and make all connections -arrows-.





2. Lightly coat the sealing rings to the crankcase with Optimol MP3 -arrow-. Carefully turn the oil separator and press it into the bore of the crankcase.





3. Fit both side fastening screws -arrows-.





4. Fit air-conditioning compressor: before installing the compressor check whether the aluminum spacer sleeve -arrow-is inserted. Grease and fit sleeve. Also guide through ground cable before installation.
5. Fit air-conditioning compressor and fasten using three M8 Torx screws (two short ones at the rear, one long one at the front). See details and tightening torques.





6. Fit drive belt. Pay attention to operating direction of used belts. Double-check that the position of the belt on the belt pulleys is correct.





7. Fit engine compartment temperature sensor with the rubber sleeve in the intake distributor 4-6.
8. Connect ground connector to intake distributor side 4-6-arrow-.
