Oil disappears 7.3l

So have this goofy Ford that like to go through oil. Fix all the top.end leaks and no more river of oil buck it is leaking fro. Somewhere. Only time it smokes is morning startup other the that she runs like top and no oil on the ground. I can hear the turbo and lots of power. But gose through 5L of oil sometimes 5 km or 230 km. The only thing I can think of is its leaking past my injectors into they cylinder and blows out the pipe but again zero smoke after her morning smoke.

Any thoughts

Check the fuel filter if it is black it would be the injector O-RINGS. Oil is mixing with the fuel and being burned. I had the same symptoms, a set of injector O-rings solved it.

Thanks for the video. I just did the glow plugs and was concerned with a small amount of smoke.
