Truck Repair: About stc valve, piston rings, blue smoke

Question
My engine is an L10 cpl 1446. I put new injectors. But every time when starting it does give me a blue smoke and rough iddling and then after that it will stay nie till the next day. WHY THAT PLENTY BLUE SMOKE? Its ugly.

Answer
Did you carry out injector travel and valve lash settings correctly after the injectors were installed prior to starting? If yes, is blue smoke accompanied by oil shortage. If yes you need to change your piston rings, or check that your turbocharger is funtioning correctly and not leaking oil.
