can you change the injector tubes and seals without removing the cylinder head on a 1.7 cdti Vauxhall combi and is it much of a job
Usually injector seals on these engines, Unfortunately you will need to change injector pipes as well.
Bad injector, head cracking, fuel system restriction, bad injector cups, or fuel pump seals.
really common fault is blown injector seals, are you getting any unwanted noises from the engine? any change in perfomance?
disconnect the battery and disconnect the fuel line hookup to the fuel rail, remove the fuel rail support bolts and electrical connection. remove the rail from the engine. pull off each injector easily replace each fuel injector with seals. don't use the old seals.
the inlet manifold could Be leaking so check the gaskets or the injector seals
The most likely problem comes from the fuel injector seals or the injectors.
No, the fuel lines, o-ring, and injector seals are not compatible with E-85.
There are seals top and bottom of injector. Either the seal is defective or loose
Black
it will expand the seals in the fuel injector pump and can stop leaks!
Usually bad injector cups. Leaking fuel seals, fuel system restriction, and bad injectors are other possibilities.
i believe it would most likely eat up the seals and probably damage the hoses.
