Ok I have a problem with a 3126b. I have oil leaking out of cylinders # 2,3 and 6. I just had the head off for bad injector cups, I have replaced the o-rings 2 times and sitll have the same problem in the same place. There is no sign of any kind of scoreing in the engine. what should I look for next. I did check the valve giudes they are loose but I have seen much worse. The engine only has 140,00 miles but lots of idle time please help. I will not sllep this weekend!!!
