Angry 855 big cam with stc

Looking for help with 855 cummins with stc. Smokes like a mother all the time. Repaired all oil leaks in the stc system and then set the overhead and still smoked. I teed in a gauge between stc valve and oil manifold and had 15 psi which o think is the minimum pressure. Felt manifold on each cylinder and one was cold so i sent all injectors to be rebuilt by a trusted shop. Put all injectors back in and problem was the same but instead of one cold.cylinder there was 3. I have a hard time believing it is the injectors because every time you start it up you have different cold cylinders. I replaced the stc valve and still the same problem. Removed turbo and exhaust manifold and one started smoking and then quit and them 2 started smoking. Possible bad cam lobes?????Is 15 psi enough oil psi to run stc system???? Truck is over fueling and i cant figure out why. Any help would be greatly appreciated.
