I will check the driver side tomorrow morning for any oily residue
looks like all I did was buy someone elses headache
so the possibilities of this being just an injector are slim I'm guessing? I really hope I dont need a rebuilt head or engine

Even if the motor is bad, I find good used 7.3's all the time 8 to 1200 bucks and they usually are just fine! I put them in customers trucks all the time, and very rarely have any serious issues

I wouldnt mind as much about this if I was in a better financial situation, but currently im in the dumps
but one thing comes back to mind.. one of the reasons I replaced the injector o rings was that I had a oil stained fuel filter along with oil consumption&blue smoke
so I did the o rings and the smoke hasnt gotten better OR worse, so what can this tell me? even if the o rings are replaced now, could the fuel and oil still mix if there is an internal issue in the injector and go back to the fuel filter housing?
maybe I have more than one issue, a dead injector and bad cylinder head? sheeeshh

What does your new fuel filter look like? Iys possible to lose oil through the injectors, not common but it does happen on occasion, but I still want to see what you find on the manifolds before you go any farther, and check the bottom of the pass side that's why you will need an inspection mirror! You might want to then consider giving Clay a call and bouncing the idea of severly worn injectors being the problem! This goes back to the skipping a couple of oil changes scenario, ^^^^^he can send them out for bench testing, and that will tell good or bad! Period! How much oil are you using per 1000miles?

what does the crosshached area on the dipstick represent? 2 quarts maybe?
in 1000 miles I would say I go through close to a gallon of oil, not an easy 1k miles though I step on it quite a bit, I just did a oil change too, I havent even put on 1500 miles since I bought this truck, maybe 1100 so far
ill check fuel filter and manifolds tomorrow, thanks for all the help so far

Any consolation, my truck does the EXACT same thing, minus the smoke that is..(knock on wood). Fuel pressures' banging at 69psi, oil press around 12psi-ish when clutch is depressed, volts are 14v...bummer for your probs dude.

Similar but not the same lack ofblow by does not nesseceraly mean all is well it just means nothing disasterous has occurred! Low compression can signify that rings are worn on a particular cylinder and that can point to the oil control ring that is failing to do it's job, if all cylinders are out of spec than that can explain the consumption and smoking issues!

I just remembered something that might come into play, when I did the injector seals I put on the new copper washers, the old ones that came off were different than the new ones.
the old ones were flush on both sides of the washer
the new one had a indent on one side and the other side had a bulge out of it, I installed them with the indentation facing the solenoid on the injector so it was flush meaning that bulge side is whats touching the injector sleeve
could oil be going past there so something? because maybe I got the wrong copper washers? or installed them on the wrong side?
I looked at the manifolds and theres no oil anywhere

Update, the truck now has a miss especially when cold and it is having a hard time starting now, cranks a while then skips/bucks and fires off with a ton of smoke as usual
Im starting to wonder if this could be the injectors again, maybe they did fail internally and are just firing oil straight into the combustion chamber
