Audi A6 - Video tutorial

Model: Audi A6 C5, MK 2 - Years 1997-2004
Part: Valve
Operation: Valve guide rubbers replacement

Actually, the so-called valve guide rubbers are real oil guards: in fact they allow the valve stem to slide in order to make it open and close without the oil ending up in the combustion chambers; when overhauling a cylinder head it is always advisable to replace them. The replacement of these rubbers requires the use of a special arc clamp capable of crushing the return spring of the valve and therefore unhooking the half-shells that fix the stem to the plate; at this point it is possible to extract the valve, the old oil seal and insert the new one after having thoroughly lubricated it with clean oil.
