Screw the adapter "T40012" into the spark plug socket. Connect a source of compressed air with a pressure of at least 0.6 MPa (6 bar). Loosen the valve crackers with a drift "VAS 5161/3" and a hammer with a plastic striker.

For the intake side
Screw in the part with the mesh "VAS 5161/6" with push fork "VAS 5161/5" into the middle threaded hole of the guide plate for FSI engines "VAS 5161/19B". Insert the mounting cartridge "VAS 5161/8" into the support plate for the FSI engine "VAS 5161/19B". Hang the pressure fork "VAS 5161/2" on the mesh part "VAS 5161/6".

On the exhaust valve side
Screw in the part with the mesh "VAS 5161/6" with push fork "VAS 5161/5" into the extreme threaded hole of the guide plate for FSI engines "VAS 5161/19B". Press the mounting cartridge "VAS 5161/8" downwards and simultaneously turn the knurled head screw of the mounting chuck "VAS 5161/8" to the right so that the tips are fixed in the valve crackers. Alternately turn the screw with the knurled head first in one direction, then in the other - the crackers will be pressed away from each other and fixed in the cartridge. Release the pressure fork "VAS 5161/2". Remove the mounting cartridge "VAS5161/8".

Using puller "3364" remove the oil seal.

If the valve stem seal puller "3364" cannot be used due to lack of space, press out the spacer pin "arrow" using a punch and impact attachment. Install the lower part of the valve stem seal puller "3364" on the valve stem seal.

Insert punch "1" into the hole in the lower part of the puller. Install the mounting lever on the puller and remove the oil seal "arrow".

Installing the oil seal
Caution! Risk of damage when installing valve stem seals. Place the plastic sleeve "A" supplied with the new valve stem seal "B" onto the valve stem.
Lightly lubricate the working edge of the valve stem seal with oil. Place the valve stem seal on the plastic sleeve. Carefully press the valve stem seal onto the valve guide sleeve using the mandrel "3365". Remove the plastic sleeve. Insert the valve spring with the valve plate. Install the dismantling and assembly device -VAS 5161 as shown in the figure.

Note: If the valve crackers have been removed from the mounting cartridge, they must first be inserted into the receiving device "VAS 5161/18". Press the mounting cartridge "WS 5161/8" onto the receiving device from above so that the valve crackers enter the cartridge.
Press down on the mounting cartridge "VAS 5161/8" using a push fork "VAS 5161/2", turn the knurled head screw of the mounting cartridge one way and the other while pulling it upwards. Remove the load from the push fork "VAS 5161/2" with the knurled head screw of the mounting cartridge still tightened. Remove the "VAS 5161" dismantling and mounting device.

Installation is in reverse order. Install the camshafts.
