smokes black at idle

Have an 03 that smokes black at idle and has a knock to it got injector balance checked and they were with in 3 point between all 8 but when you shut number 4 injectors off smoke goes away and runs smooth. So pulled even bank apart and there is engine oil in number 4 injector line is this a cracked injector or something else and all 8 injectors were replaced a year and a half ago
