- The spark plug factory is a crucial component of the automotive industry, responsible for producing the tiny yet powerful devices that play a key role in the functioning of internal combustion engines. These small but important parts are critical for igniting the fuel-air mixture in the engine cylinders, creating the combustion needed for the vehicle to run smoothly.
Special exceptions still apply within the Volkswagen group. With PTFE oil seals, an aluminium or plastic housing is used in many different engine series. The Top Dead Centre (TDC) signal is no longer measured at the flywheel, but directly using a sensor on the rear crankshaft flange and integrated sensor in the oil seal. Special procedures and tools must be used for the disassembly and assembly of these parts.

Thoroughly clean the sleeve at the back of the pulley, and look for any roughness on it where it touches the seal. If necessary, smooth it with fine wet-and-dry abrasive paper.
