Hi, we are facing a problem of C7 injector failure and have witnessed it on atleast 05 engines wherein a minimum of 02 and max all 06 injectors were found cracked. In all the cases the engine was found emitting black smoke and not attaining desired speed. On opening up injectors were obeserved cracked. Can anyone help pinpoint the reasons / suggest wayahead to prevent this from happening? the engines are about 06 years old and have clocked only about 200 - 1800 hours till date. Case studies of such failures, if repoted by anyone else, may also be shared. Is it a frequent and a known problem on these engines?
