Re: 1996 f250 powerstroke vanishing oil.
That is how I got my 97 F350
She "drank" almost all 15 quarts of her oil
If you look at how the HEUI
injector works....there is over 3000 psi
in the high pressure oil side of things and only 68 psi
of fuel rail pressure
So when the O rings that separate the high pressure oil from the fuel system fail....well it does not take long for 3000 psi
worth of oil pressure to feed oil into the combustion chambers.
Basically your crank case oil becomes fuel
Injector O rings are the cause
If you have hard starts when cold then it maybe time for new injectors (worn poppet valves)
Also check the coolant cups very carefully when installing new O rings, you must get everything very very clean for the O rings and copper crush washer to seal.
I went through the wringer with my 97.......only had my injectors out like 4 times now shes a hauling SOB daily driver :)
