So I've notied my truck is using oil. No leaks at all. Everything in the motor is dry around the HPOP, HPOP lines, Valve Covers etc. I change the oil every 5k, and when I do, I ensure that the level is at the top of the full mark. I'm getting close to changing it, and I am now almost at the bottom of the "normal operating range." Now, I know that some oil consumption is normal for these trucks b/c of blowby etc, but I have a theory here...
I've still got the issue of revving it and having it "hiccup" and belch out blue/white smoke. And you can tell that it happens when the chip is off, but just not as pronounced. In any case, where you would normally see a "soot" buildup on the back bumper that you can wipe away with your finger (which is what I always had until I had the injectors replaced), I now have a discolored bumper that has a oily residue. You can tell its oil cause right where the exhaust blows out, the bumper looks like a rainbow!
So, ever since I've had these injectors replaced (#1,5,7) the truck just hasnt been the same. I know its not chip cause I can replicate the problem without it (just not as pronounced), and I have read before that if an injector is out of whack, it can cause oil consumption. In the past, it has passed the contribution test, and I was told short of replacing all injectors, its gonna be tough to find. I had the orings replaced a few months ago, but didnt see an improvement.
Your thoughts?
***On edit: Also forgot to mention that EGT's just have been higher than normal as well...makes me think its buring too much of something?

If you're getting oil in the cylinders it'll get burned the hiccup in the running is likely unrelated to the oil that is unless your valve seals are leaking and oil is dripping down the valve stems into the intake & exhaust.
