Smoke
I just bought another 7.3 and its pullin some stuff on me. When I start it its not smoking or surging or anything but after it runs about 3-4 minutes it will start smoking blue, but the tricky part is that the blue smoke does not smell like oil at all it is clearly fuel smoke by scent it burns your nose and eyes. Now I think it is bad injector o-rings because of the blue smoke and fuel scent, but I want to know what yall think before I dig into it possibly chasing the wrong thing. the truck is a stock 96 with 195000 on it and injectors appear to be pretty sound because this truck will **** *** its just smoking.

Blow by is not caused by injector O rings.
Run a cylinder contrubution test, buzz test, compression test and leak down test.
That will tell you all you need to know.
I would bet you have some injector issues, but I doubt its the external O rings, more then likely some internal issues with the injectors with 200k.
