Hi, my name is***** your mechanic automotive expert, and I will be happy to assist you today. In some cases, I may need more information to assist better. I apologize for any delay.
I try to be here most weekdays and some weekends. If you respond and I do not respond back right away I will do so as soon as I can.
Dear customer, first the most important thing is to observe the injectors to see if the injectors allowed the passage of metal shavings to the cylinders of the engine.
Second, there are two ways to proceed, one is replacing the entire fuel rail and the other is disassembling and cleaning it carefully, it is best to replace the rail because many times the metal waste damages the injection components and their seals, this causes the fuel is leaking at times and it can be dangerous to stay that way, but when we do not notice the leakage and we do not realize it.
Then the tank is dismantled and a very good cleaning is carried out, in turn, the whole body of the pump and the fuel pump itself must be replaced.
The pressure regulator must also be replaced if it is within your budget to replace all the injectors do it.
This is the best way to proceed, the worst is as I told you at the beginning, that the waste has entered the engine and can damage the cylinder and a valve, this leads to quite expensive repairs, so I recommend that First of all, verify that these metallic residues have not passed from the injectors to the cylinders.
