Special tools and workshop equipment required
- Spark Plug Removal Tool3122 B
- Valve Seal Removal Tool 3364
- Valve Stem Seal Driver 3365
- Adapter T40012
- Torque Wrench (5-50 Nm) V.A.G 1331

Removing
To remove the valve stem seals, the following components must be removed as follows:
- Intake valves cylinder 1: Transport strap
- Intake valves cylinder 5: Camshaft adjustment valve 1 -N205-
- Exhaust valves cylinder 5: Secondary air injection solenoid valve -N112-
-- Remove the camshafts. Refer to CAMSHAFTS .
-- Remove the roller rocker arm and lay them on a clean surface. Make sure that the rocker arms are not interchanged.
-- Remove the spark plugs using the spark plug removal tool 3122 B.
-- Install the guide plate for FSI engine VAS 5161/19B using the knurled thumb screws M6 VAS 5161/12 to the cylinder head as shown.
-- Adjust the piston of the respective cylinder to Bottom Dead Center (BDC).
-- Install the adapter T40012 into the spark plug hole and connect the compressed air (minimum 6 bar).
-- Loosen any stuck valve retainers using the punch VAS 5161/3 and a plastic mallet.
-- Install the retainer VAS 5161/6 with the guide forks M6/M8 with threaded studs VAS 5161/5 into the guide plate for FSI engine VAS 5161/19B.
-- Insert the assembly cartridge VAS 5161/8 into the guide plate for FSI engine VAS 5161/19B.
-- Engage the pressure fork with lever for assembly cartridge VAS 5161/2 on the retainer VAS 5161/6.
The pressure fork with lever for assembly cartridge VAS 5161/2 must engage on the exhaust side as illustrated.
-- Press down the assembly cartridge VAS 5161/8. At the same time, turn knurled bolt on the assembly cartridge VAS 5161/8 clockwise until the points engage in the valve retainers.
-- Lightly move the knurled bolt on the assembly cartridge back and forth, this causes the valve retainers to be pressed apart and captured in the cartridge.
-- Release the pressure fork with lever for assembly cartridge VAS 5161/2.
-- Remove the assembly cartridge VAS 5161/8, valve spring retainers and valve springs.
-- Remove the valve stem seal using the valve seal removal tool 3364.
-- In the event the valve seal removal tool 3364 cannot be used due to space constraints, drive the out pin -arrow- using a drift and remove the impact device.
-- Place the lower part of the valve seal removal tool 3364 onto the valve stem seal.
-- Insert a drift -1- into the bore in the lower part of the valve seal removal tool.
-- Using the drive -1- as a lever, pull out the valve stem seal -arrow-.
Installing
-- Place the plastic sleeve -A- on the valve stem to prevent damage to the new valve stem seal -B-.
-- Lubricate the sealing lip of the valve stem seal -B-, insert it into the valve stem seal driver 3365 and carefully slide it onto the valve guide.
-- Remove the plastic sleeve -A-.
-- Insert the valve spring and valve spring retainers.
-- Install the valve cotters asm/disasm device VAS 5161 components as shown.
If the valve retainers were removed from the assembly cartridge, they must be inserted into the valve insertion device VAS 5161/18 next.
Press the assembly cartridge VAS 5161/8 onto the valve insertion device from above and take up the valve retainers.
-- Press down the assembly cartridge VAS 5161/8 using the pressure fork with lever for assembly cartridge VAS 5161/2, knock lightly against the assembly cartridge in the lower area, rotate the knurled bolt on the assembly cartridge back and forth and pull upward while doing this.
-- Release the pressure fork with lever for assembly cartridge VAS 5161/2 with the knurled bolt pulled.
-- Remove the valve cotters asm/disasm device VAS 5161 components.
The rest of the installation follows the reverse of the removal procedures. When doing this note the following:
-- Remove the locking pin T40069 from the rear of the cylinder block and install the locking bolt.
-- Fill the coolant. Refer to one of the following:
- Jetta from MY 05 through 10, Jetta SportWagen (US)/Jetta Wagon (Canada) for MY 09 and Jetta SportWagen (US)/Golf Wagon (Canada) from MY 10, refer to DRAINING AND FILLING .
