As Quito Lid Valves and Injector Ford 1.4 TDCI

Ola turns out that I want to get the injectors from my Ford Fiesta 1.4 TDCI of 2008, but it turns out that I have released all the screws to be able to remove the lid from the valves and it has not been possible, to see if someone can help me, I do not know if it will be that it is stuck and it is time to do it enough to leave and leave the injectors to be able to remove them and change the copper washers.
