Ever since I put the 6.9 i my truck it has had a bluish white smoke at idle and at take off. It was covered up a little bit when I had bad injectors, but has been more noticiable since I put new ones in that I bought from Russ. At first I was figuring that the smoke was coming from a worn injection pump, but Ive swapped 3 of them on and off of the truck. The smoke level has gone down a bit with pump I have now, but it still there. The smoke itself smells like raw fuel. Ive cleaned the cdr valve and run diesel kleen and atf every tank. I figured that the bluish smoke was from bad valve seals, but would that cause the exhaust to smell like raw fuel?
