What is the engine serial number?
Thank you. Yes the correct adjustments will correct the smoke, the injector old down torque is and based on your CPL # ***** 1185 the injectors get adjusted to 90 inch lbs. The intale valve lash is 14 thousands and the exhaust lash is 27 thousands.
The injector hold down torque is 168 inch lbs
If you adjusted the injectors to 33 ft lbs you have damaged the injectors. and they may need to be replaced again. Please don't forget to rate my service

Well you may have air in the STC rail, or the STC valve is failing. Can you Isolate it to a cylinder. You could have got bad injector out of the box. This is very common.
Thank you, ***** ***** Cummins replaces all injectors it is procedure to rebuild or replace the STC valve.
Sure it should be done at overhaul time. You will need to replace pistons ,cam injectors,turbo fuel pump. and cost alot of $$$$ your better off buying a recon engine and dropping it right in. It will save you $$$$$
