Removal
Remove valve cover. Place crankshaft at TDC. Remove timing
chain from camshaft sprocket. Remove camshaft bearing caps. Remove
camshaft.
Inspection
Check camshaft bearing oil clearance. See CAMSHAFT table
under ENGINE SPECIFICATIONS at end of article. If oil clearance
exceeds specification, install new camshaft and recheck clearance. If
clearance still exceeds specification, replace cylinder head.
Installation
1) Lubricate all contact surfaces. When installing bearing
caps, ensure identification mark on bearing cap is readable from
exhaust manifold side and arrow points toward vibration damper. See
Fig. 13.
2) Tighten bearing caps No. 1, 3 and 5 alternately in a
diagonal sequence to 15 ft. lbs. (20 N.m). Repeat procedure for
bearing caps No. 2, 4 and 6.
3) To complete installation, reverse removal procedure.
Ensure timing marks are properly aligned. Before starting engine,

Cylinder Head
Clean all gasket mating surfaces. Check cylinder head for
warpage. Ensure warpage does not exceed .004" (0.1 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 at end of article. If
valve guide 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 at end of article.
Valve Seats
1) Check valve seats before any other cylinder head service.
Insert the valve and hold firmly against the valve seat. Measure valve
stem tip-to-cylinder head distance. See Fig. 14.Fig. 14: Measuring Valve Installed Height
Courtesy of Volkswagen United States, Inc.
2) This measurement determines installed valve height.
Subtract measured distance from minimum specification. See
MINIMUM VALVE INSTALLED HEIGHT table.

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.

1) Measure ring end gap. Measure ring side clearance with
piston. Replace if necessary. See PISTONS, PINS & RINGS SPECIFICATIONS
table under ENGINE SPECIFICATIONS at end of article.
2) Install rings on piston with OBEN or TOP mark facing
upward. Recessed edge on outside of center ring must face piston pin
(down). Position ring gaps on piston at 120 degree intervals.
Connecting Rod Bearings
Mark rod caps for reinstallation. Use Plastigage to measure
bearing clearances. Measure connecting rod side play. Replace or
machine as necessary. See CRANKSHAFT, MAIN & CONNECTING ROD BEARINGS
table under ENGINE SPECIFICATIONS at end of article. Tighten evenly to
specification in several steps. See TORQUE SPECIFICATIONS table at end
of article.
Crankshaft & Main Bearings
Main bearing caps are marked with matching journal for
installation in original position. See Fig. 16. Measure crankshaft end
