VALVE LIFTERS
Removal & Installation
Remove camshaft. See CAMSHAFT. Remove valve lifters from
cylinder head. Note position of each lifter. If lifters are reused,
they MUST be installed in original position. If replacement lifters
are charged with oil, allow 30 minutes for lifters to bleed down
before starting engine. Otherwise, valves may come in contact with
pistons. To complete installation, reverse removal procedure.
WATER PUMP
NOTE: Coolant/water mixture should be used at all times.
Page 11

using Spanner Wrench (VAG 1590). Remove water pump bolts. Push engine
toward left side and remove water pump.
Installation
When installing motor mounts, ensure recess on engine bracket
fits into mounting tab of bonded rubber bushing. Hand tighten motor
mount bolts and light rock engine to ensure motor mounts are fully
seated. To complete installation, reverse removal procedure.
Removal & Installation (Golf & Jetta - AFP Engine)
1) Obtain radio security code. Turn ignition off and wait for
20 seconds. Disconnect negative battery cable. Drain cooling system.
2) Remove accessory belt. Remove pulley retaining bolts and
pulley from Coolant pump. Remove coolant pump bolts and coolant pump
from engine block.
3) To install, reverse removal procedure. Tighten bolts to
specification. See TORQUE SPECIFICATIONS.

Removal & Installation
1) Remove center, left and right damping pans. Drain oil.
Remove oil pan bolts. Remove oil pan using a rubber hammer if
necessary. Remove sealant residue from cylinder block and oil pan.
Ensure surfaces are free from grease and oil.
2) To install, apply 2-3 mm thick silicone bead around
sealing surface of oil pan. Immediately install oil pan and lightly
tighten all bolts. Ensure oil pan is flush with cylinder block.
Tighten bolts to specification. See TORQUE SPECIFICATIONS. To complete
installation, reverse removal procedures. Allow sealer to dry 30
minutes before installing engine oil.
OVERHAUL
CYLINDER HEAD
Cylinder Head
Clean all gasket mating surfaces. Check cylinder head for
warpage. Ensure warpage does not exceed .0039" (.100 mm).
Valve Stem Oil Seals
With valve springs removed, remove oil seals using Valve Seal
Remover (3047A). To install new oil seal, slide plastic sleeve over
valve stem. Lubricate new oil seal. Using Valve Seal Installer (3129),
push oil seal on valve guide.
Valve Guides
1) Check valve-to-guide clearance specification. See
CYLINDER HEAD table under ENGINE SPECIFICATIONS. If valve guides have
previously been replaced, replace cylinder head.
2) To replace valve guide, press guide out from camshaft
side. Lubricate guide and press in cold cylinder head (from camshaft
side) until shoulder makes contact. DO NOT exceed one ton pressure.
Ream guides to proper valve-to-guide clearance. See CYLINDER HEAD
table under ENGINE SPECIFICATIONS.
Page 12
Valve Seats
1) Check valve seats before any other cylinder head service.
Insert valve and hold firmly against valve seat. Measure valve stem
tip-to-cylinder head distance. See Fig. 15. This measurement
determines installed valve height. Subtract measured distance from
minimum specification. See MINIMUM VALVE INSTALLED HEIGHT table.
2) The difference is maximum refacing allowable for valve and
seat. If valve installed height is too low or too high, lifters will
not work correctly. Replace cylinder head assembly.

Valves
Measure valve length, stem diameter and valve margin. If not
within specification, replace valves. Lap valves by hand or replace as
necessary. See VALVES table under ENGINE SPECIFICATIONS.
HYDRAULIC LIFTER TEST
To determine weak or noisy lifter, position camshaft lobe
high point upward. Using a piece of wood, push lifter down. See
Fig. 16. If lifter moves down more than .004" (.10 mm), replace
lifter. If lifter moves less than .004" (.10 mm), lifter is okay.
Repeat procedure for remaining lifters.
CAUTION: If new lifters have been installed, engine must not be
started for 30 minutes. Otherwise, valves may come in contact
with pistons.

2) Mark piston in relation to pin. Remove circlips from ends
of pin bore. Use Piston Pin Replacer/Installer (VW 222A) to remove and
install piston pin. If pin is too tight, heat piston to 140øF (60øC).
Ensure rod is properly positioned with piston.
Fitting Pistons
Measure clearances with cylinder block supported on work
bench. Check clearance of piston-to-cylinder bore. Piston diameter is
stamped on top of piston in millimeters.
