Late 99' PSD Burning Tons of Oil! Help Please.

[Black93hardtop]

Im hoping I can get some advise in the right direction. Im leaning hevily towards turbo seal(s) but Id llike to hear some opinions so I dont jump to conclusion.

My 99 F-250 just started burning TONS of oil a couple days ago. I didn't realize how bad it really was until the thing died because it ran itself so low on oil it couldn't feed the HPOP to fire the injectors! It ate 11 quarts in 20sih miles! Odd thing was that I topped it back off to get it home and for about 4 miles it wasn't burning ANYTHING! then it just started again. It fixed itself for a few miles? Well, its home now and I need to fix this thing.

Intercooler pipes are loaded with oil BUT my friends 02' PSD doesn't use hardly any oil in 10K and its pipes are loaded too. I assuming this is just from the crank vent setup. Yes its smoking blue, bad. The truck does have over 200K on it but I do not know if this turbo is original.. Looks to be though. The truck is bone stock, zero modifications. Turbo still spools and truck makes good power besides the heavy oil consumption. Starts rough not and won't let you throttle it up for a few minutes... Never did that either. Went from perfect to this.. Help please.

Short history.. Until this, the truck used ZERO oil, starts immediatly, ran perfect, got 17 city 20 highway MPG. No issues and always smooth sailing. Good power.

Thanks,

I'm having the same issue. So replaced the turbo. Upgraded it to a 38r. Ended up being bad rings. So now I've got a upgraded turbo atleast when I figure out what ima do with the engine.

check your fuel filter for oil.

I cannot see how its the rings, The thing ran perfect then it just one day decided to burn oil! The fact that it stopped for a while then returned doesn't make me lean towards rings at all. It still starts quick and sounds healthy. Plus the amount of oil its burning seems like it would have to be literally pumped into the engine. I don't think you could burn near 3 gallons of oil in 20miles with just bad rings. Did you do a compression test to confirm rings? How bad was your oil consumption?

I will tomorrow. Care to elaborate how oil would flood into the fuel system?

as mentioned, check the fuel bowl for oil
oil can leak past an injector o ring and into the fuel rail.

also, try starting the engine. pop the hood and remove the oil fill cap. check for excessive blow by

No blow by, removed oil cap and it is good. Practically zero pressure or puffing.

I will check the fuel bowl tomorrow for sure and post results.

through your injector orings. oil under pressure blows by the injector rings and backfeeds into the fuel system. Its the first place i check when i see massive oil consumption and blue smoke.

Pulled fuel filter cap off and it looked very clean and was just diesel. No oil.

Also, when driving it it smokes a steady amount but under boost it pours blue smoke! I have not driven it since all this because Im scared of doing more damage. Im just glad the way these engines work with the LPOP feeding the HPOP that when it ran low on oil it just dies instead of me driving it until the engine siezed!

Anything else to look at guys? Conclusions?

Thanks,

have you pulled off the intake tube and checked the turbo for any play or excess oil?
