Hello, I have a 2009 Ford Econoline, Diesel Engine 6.0 Lts., That arrived at the workshop with the toothpray (zipper) of the slaughtered engine, the tooth was changed, the converter (turbine) was checked and no additional damage was found, it was detected that only the start produced a more severe noise than normal, it was explained to the person in charge of this vehicle (it is an ambulance) and He worked only a few days and was Danificado novamente com o mesmo padrão de ruptura, gostaria de saber se algum parceiro já teve um problema semelhante antes, para compartilhá -lo comigo, obrigado.
