Hello guys, my Astra J SPorts Tourer engine damage and the fault picture and its probable emergence leave me no rest, I need your swarm knowledge. Car was in inspection (oil, candles, air filter). From the workshop home about 10 km everything ok. The next day no 50m driven, engine lamp on, (engine runs only on 3 pots). Again to the workshop, error confirmed does not run round, a Zilinder does not build up pressure. Zilinderkopf dismantled and found the following (s Bilde r): Apparently a round metal ball got into the combustion chamber and played roulette there. Has anyone ever seen such a thing of you ? Workshop means that the “charge pressure control valve” was defective and lost this small metal part which then hit me engine/valve. Could that have been so ? or did the workshop change perhaps by candle what fell into the combustion chamber (where is worked happen faults). Workshop says, whatever caused this ? for a long time in the engine not only have been 20 km since the impact points are already so oxidized. Your opinion ? I am curious.
