Procedure
Notes:
   When repairing engines with leaking valves it is not sufficient to just work on or
   replace valve seats and valves. With longtime engines in particular it is necessary to
   check valve guides for wear.
   Only finish valve seats until a correct contact pattern is achieved. Before finishing
   valve seats you need to calculate the allowable finishing measurement. If this
   measurement is exceeded, correct functioning of the hydraulic valve clearance
   balancing cannot be guaranteed and you must replace the cylinder head.
Calculating the maximum allowable finishing measurement
- Insert valve and press firmly against the valve seat.
  Volkswagen Jetta, Golf, GTI 1999, 2000
  2.8 Liter VR6 2V Engine Mechanical, Engine Code(s): AFP
  Valve gear, repairing (Page 15-32)
Notes:
If the valve is being replaced during repairs, use a new valve for measuring.
- Measure distance -a- between valve stem end and upper edge of cylinder head.
- Calculate the maximum allowable finishing measurement from measured distance
  and minimum measurement.
Minimum measurements:
   Intake valve: 33.9 mm
   Exhaust valve: 34.1 mm
Measured distance -a- minus minimum measurement = max. allowable finishing measurement.

- Clean old sealant from 3 mm bores in the cylinder head gasket.
Notes:
With the cylinder head installed, the bores in the cylinder head gasket are only partially visible.
- Install camshaft sprockets with camshaft roller chain      page 13-10 , adjust timing.
- Fill 3 mm bores in the cylinder head gasket with sealant AMV 188 001 02.
- Coat cover sealing surface with AMV 188 001 02.
Notes:
Make sure that the oil duct sealing O-ring is seated in the cover.
- Install cover, start all fastening screws and lightly tighten by hand.
- First tighten the M8 fastening screws to 25 Nm, then tighten the M6 fastening screws
  to 10 Nm.
- Install camshaft roller chain tensioner and tighten to 30 Nm.
Notes:
After installing new valve lifters, do not start the engine until after about 30 minutes. Hydraulic
balancing elements must become properly seated (otherwise, valves will make contact with the
piston).

Checking hydraulic lifters
Special tools, equipment, test and inspection devices; required accessories
  Feeler gauge
  Wooden or plastic wedge
Test procedure
Notes:
     Valve lifters must be replaced as units (they cannot be adjusted or repaired).
     Intermittent valve noises during engine startup are normal.
- Start the engine and let it run until the radiator fan has turned on once.
- Increase the engine speed to approximately 2500 rpm for 2 minutes.
If the hydraulic lifters continue to make noise, find the faulty lifter as follows:
- Remove the cylinder head cover          page 15-8.
- Turn the camshaft at the oscillating damper fastening screw clockwise until the valve
   lifter cams being tested are in the upper position.

- Determine the clearance between cams and valve lifters.
- If the clearance is greater than 0.2 mm, replace the valve lifters. If the clearance is
  less then 0.1 mm or no clearance is determined, continue the test as follows:
- Push the valve lifters downward with a wooden or plastic wedge. If you can feel
  unrestricted motion of more than 0.2 mm until the valve opens, replace lifters.
Notes:
After installing new valve lifters, do not start the engine until after about 30 minutes. Hydraulic
balancing elements must become properly seated (otherwise, valves will make contact with the
piston).

Valve guides, checking
Special tools, equipment, test and inspection devices; required accessories
   Universal gauge retainer VW 387
   Gauge
Test procedure
- Insert a new valve into the guide. Valve stem end must be flush with the guide.
  Because of the varying stem diameters, use only intake valves in intake guides and
  exhaust valves in exhaust guides.
- Determine tilt clearance.
Max. wear:
   Intake valve guide = 1.0 mm
   Exhaust valve guide = 1.3 mm

Removing
- Clean and check cylinder head. Heads whose valve seat rings cannot be finished
  any further, or heads which have already been finished to the minimum
  measurement (height       page 15-27 , item -7-), or which already have KD valve
  guides installed, are unsuitable for valve guide replacement.
- Press worn valve guides out from the camshaft side by using driver 3121.
Installing
- Sprinkle new guides with oil and press them up to the sleeve into the cold cylinder
  head. The cylinder head must be laying down flat during this procedure.
Notes:
After the guide is in place with the sleeve, the pressure of pressing down cannot exceed 1.0 t,
otherwise the sleeve might break off.
- Ream the valve guide with hand reamer 3120. You must use diluted soluble oil
  during this procedure.
- Finish valve seats      page 15-31.

Removing
- Remove camshafts        page 15-34.
- Remove valve lifters (do not mix up) and place aside with the running face facing
  down.
- Remove spark plugs with spark plug wrench 3122 B.
- Bring the piston of each applicable cylinder into the "Bottom Dead Center" (BDC)
  position.
- Insert mounting device 2036 and adjust the bearing arrangement to the stud bolt
  height.
- Screw the flexible pressure tubing VW 653/3 into the spark plug thread and provide
  continuous pressure (min. 6 bar).
- Remove the valve springs with mounting lever VW 541/1A and thrust piece VW
  541/5.
Notes:
Loosen binding valve collets (keepers) by applying light hammer blows to the mounting lever.
- Remove valve stem seals using extruder 3047 A.
