Replacing valve stem seal Removal with cylinder head removed Special tools and workshop equipment required t  Valve lever -MP1-211 (VW 541/1a,/5)- t  Valve supporting plate -MP1-218 - t  Assembly device for valves -MP1-213 (2036) - t  Valve stem seal extractor -MP1-230 (3364)- t  Valve stem seal insertion tool - MP1-233 (3365)- l  Cylinder head and camshaft removed l  Components removed (intake manifold, exhaust manifold, spark plugs etc.)   Note The procedure is illustrated on the cylinder head with two valves.

–  Fit cylinder head onto the valve supporting plate.

–  Screw on assembly device for valves -MP1-213 (2036) -.    Always use cylinder head cover screws (M7) -1- with 4 M8 washers -2-. –  Place the valve lever -MP1-211 (VW 541/1a,/5)- on the valve spring and press the valve spring together. –  Remove the safety valve collets.   Note Release collets that are tight by striking with light blows of a hammer on the valve lever.

–  Pull off valve stem seal with extractor for valve stem seal -MP1-230 (3364) -.    Press sleeve -1- down slightly during this step. Install

–  In order to avoid damage to the new valve stem seals, fit the supplied plastic sleeve -A- onto the valve stem. –  Oil valve stem seal -B-, insert into the valve stem seal insertion tool - MP1-233 (3365) - and carefully push onto the valve guide. –  Remove plastic sleeve. Further installation occurs in reverse order. Removal with cylinder head installed Special tools and workshop equipment required t  Supporting device -MP9-200 (10-222A)- t  Spark plug wrench, e.g. - 3122B- t  Blank holder for valve spring -MP1-229 (3362) - with pressure plate -MP1-229/1 (3362/1)- t  Valve stem seal extractor -MP1-230 (3364)- t  Valve stem seal insertion tool - MP1-233 (3365)- t  Counterholder -T30004 (3415)- with replaceable bolt -T30004/1 (3415/1)- t  Counterholder -MP1-216 (3036)- t  Pressure hose -MP1-210 (VW 653/3)- t  Extractor -T10094A- –  Remove V-ribbed belt → Chapter. –  Remove cylinder head cover → Chapter. –  Unscrew the spark plugs with spark plug wrench -3122B -. –  Remove roller rocker arm and place on a clean surface. Make sure the roller rocker arms are not interchanged. –  Position piston of the relevant cylinder in bottom dead centre.

–  Screw on blank holder for valve spring -MP1-229 (3362) - with pressure plate -MP1-229/1 (3362/1)-. –  Screw the pressure hose -MP1-210 (VW 653/3)- in the spark plug thread. –  Connect pressure hose to compressed air (min. 0.6 MPa (6 bar) overpressure) and remove the valve springs with blank holder for valve spring -MP1-229 (3362)-. –  Pull off valve stem seals with extractor for valve stem seal -MP1-230 (3364)-. Install –  Insert the supplied plastic bushings on the relevant valve stem. This will prevent any damage to the new valve stem seals.

–  Insert the new valve stem seal -B- in the insertion tool for valve stem seal - MP1-233 (3365) -. –  Oil the sealing lip of the valve stem seal and carefully slide onto the valve guide -A-. Install cylinder head cover → Chapter. Installing the camshaft sprockets, setting the timing → Chapter. Further installation occurs in reverse order.
