Help!! 7.3 Major Oil Consumption!

[Mykol]

A frient has an '03 7.3 with around 250k miles. He says it runs perfect, no smoke or miss but uses 3 gallons of oil in 50 miles! He may drive 500 miles with no oil consumption, then next 50 mile drive it may lose gallons. No visible leaks or anything. Please help, because he is now afraid to drive anywhere! Thanks

If it isn't leaking, it's eating it. Maybe injector related?

does it smoke at idle or under throttle? Not black smoke, white or grey smoke. check the tail pipe, does it feel sticky inside like it has a residue? also, you sure no leaks? check under the rear of the truck it may have been pushed back there with the wind from driving.

[Mykol]

He says only normal light smoke under throttle (fuel I am pretty sure) and no signs of leaks...

[Mykol]

Is there any chance that this may be caused by bad turbo seals?

[jesilvas]

Yea but it would be coming out of the tail pipe as residue or smoke if it was turbo seals or injector related. There HAS to be either leaks or smoke/residue. I don't see any other way there isn't.

It was suggested to look in the fuel filter bowl for engine oil. If oil is in the fuel bowl, then it is likely injector o-rings. There was, so now my question is- Is there a write up or video on how to remove the injectors and replace the o-rings?

[HVAC SuperTech]

I think theres a write up in the tech files. look in that section.

Atest to that my truck started that after a head on crash. Trying to find the problem myself. Shop give me a list that cost 2400 and I found nothing on it fixes my problem. Still searching
