Valve Guide Servicing

WARNING: This page is about a different car, the 1983 Volkswagen Scirocco, 1983 Volkswagen Rabbit, 1983 Volkswagen Quantum, 1983 Volkswagen Pickup, and 1983 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.

Clean valve guides before making measurements. To measure guide, attach a mounting device with a dial gauge (VW689/1) to mounting surface of cylinder head. Insert a new valve until end of stem is flush with end of valve guide.
Rock valve head against dial indicator and check amount of rock recorded. Maximum allowable rock is .039" (1.0 mm) for intake valves and .051" (1.30 mm) for exhaust valves. Proper valve guide diameter is .315"-.316" (8.01-8.04 mm).
Use a press and adaptor (10-206) to remove and install valve guides. To remove guides, press out from combustion chamber side of head.
Coat new valve guides with engine oil. Press new guides into cold head from camshaft side. Make sure shoulder of guide meets firmly with top of cylinder head. Ream guides to uniform inside diameter.

NOTE: DO NOT use more than 1 ton pressure once guide shoulder is seated or shoulder may break.
