Is the smoke oil or diesel? You should be able to smell the difference. Have you tried the quick check where you place the oil cap upside down on the filler tube while the engine is running and see if it sits there or blows off with pressure? If not you need to do that, it only takes a minute and will help determine the health of your engine.

No oil in coolant then it's just not a super bright green fresh coolant color. All my fluids seem fine minus the loosing of oil. If the injector rings where causing it to loose the oil would it be burning the oil out the tail pipe with fuel? I can smell the smoke and it doesn't smell exactly like fuel and it doesn't smell exactly like oil. Maybe it's just really hard to tell the difference... Or ?

There is a test to test your injector O rings. It's dubbed the Cody test in the name of the member here who brought the idea to us. You remove the HPOP hoses and pressurize the heads one at a time with air pressure. If you're losing oil there you should be able to hear it gurgling. I have no first hand experience with a failure (I have performed the test) so I can't tell you exactly what it sounds like. And since it is a dead end a small oil bath is possible if you don't cover the joint with a rag during the test.

Time to pull your fuel filter and see if it's black and oil stained. It is possible for bad injector o-rings to let fuel and oil mix. Oil has a higher pressure so you'll have signs of oil in the fuel filter. You'll also have fuel in the oil from key on before you start it up, so an oil change might be in order too. (sounds like you've already got a head start on the oil drain part).
If fuel filter is nice and clean, then I'd be looking at the tail pipe for any signs of oil from possible turbo issues or o-rings.
Can you do a cylinder contribution (perdel) test?

Here is what the Cody test sounds like with a cut O-ring.
