injector noise

[306clot]

When i changed my injectors for some 076 ones, i needed a diesel specialist to come out and remove one of the injectors as it was seized solid, we talked about the ticking and he stated that my old ones were indeed corroded inside witch would have reduced their performance but however even brand new injectors will tick due to the design of a diesel common rail injector, the more fuel that they are required to inject and the quicker the louder they will get. 


For example he just had some brand new tractor ones fitted and he said they are nearly deafening when up close, thats just the way they are. Some manufactures just counteract the problem with lots of sound ending
