Need Help Sprinter 313 Injector Carbon Buildup
Every 10,000 Km or so, severe carbon buildup occurs around the injector seats on all the cylinders. Seems like there is substantial pressure leak through the injector.
Last time seals were replaced and injectors properly fitted, yet solid carbon buildup again. Diesel used is of good quality and don't have problems with other vehicles. Perhaps a badly designed clamp system that holds the injector in place? Vehicle reaches a point where it doesn't start because pressure leak through the injector seal. Is it possible that the wrong size seal is being used. Parts are always bought directly from MB Agents.
