2000 7.3 Oil coming out of the exhaust

I did a oil change a week ago and now the truck is 6 quarts low and I see oil coming out of the exhaust!! I just bought the truck a month ago and now it is doing this.

remove the air cleaner boot from the turbo. grab the compressor wheel at the shaft and feel for excessive play

if not that you can figure a possible injector sealing issue
from what I have read about that condition

good luck

the thing is that because he's seeing raw oil at the tailpipe, this points more towards an issue with the turbo. since it's not likely being burned in the combustion chamber. the turbo would be the most likely area for oil to exit the exhaust in this way, after the combustion chamber.
if he were down oil and blowing blue, then yes, absolutely i'd say check the fuel bowl for oil cross contamination due to injector o rings. or check for blow by

Well the turbo seemed to be snug. Put it back together and it took it for a drive. It ran great and only had moisture coming out of the exhaust. But it lost 5 quarts of oil in a 2 hr drive. No leaks under truck I can see!! Taking to my mechanic in the morning and will let you know what he says. Thanks for the advice.

injector o rings , you won't see oil in the fuel at the fuel filter, there is no return back to the fuel bowl from the heads . an obs will show oil at the fuel bowl if injector o rings are leaking

If the injector O rings are leaking oil, would it be smoking? I was pondering on it may be a high pressure oil line leak? If I'm lucky!! Lol

yes it would smoke, you are burning fuel and the oil . I lost almost 2 gallons before it started to run bad and i noticed smoke . You can't run these motors out of oil to a point of destroying the motor , once the oil gets low, you won't have enough to supply the HPOP and it will shut down. A HPO line leak will dump oil in the valley and you will see it dripping.A 6.0L can have a HPO leak under the valve cover and not leak externally.

i have to agree. injector o ring(s) would be the next likely suspect.
