Where did you get the orings from? What did you use for lube? And how much oil is it using? Still kind of waiting for an answer to that one lol

1 gallon every 60 or so miles. Ford motorcraft o-rings...always. my 6.0 customers get multi layered steel ford motor craft as well... off subject but just 2 let u know. Ford parts...corn head greese. Its used in agriculter. Ive had the best luck with it. Besides,there viton o-rings. I dont even think the vasaline effects them like they say it does.
Before anyone ask. Yes,there torqued to spec

1 gallon every 60 miles?

If it's injector orings, the pull the fuel filter and make sure. That much oil is going to dye a filter real quick.

Also, if your losing THAT much oil through injector o-rings, you'd know. It probably smoke like a trailer queen and run like crap.


Considering these truck don't run when they get 2qrts low... I'm assuming your topping off every 30 miles?

Hmmm...

If the fuel filter is black there is only one way it's getting there. I've never heard of warped cups but you never know. I guess it could be a possibility.

Me either brother. How would you diag a fuddged inj? Thats showing no failure on a high end scanner. Imo the best scanner out there.

WTf do i do next? Well,it would be pricey but mr jim in ohio. Bench test....

Easiest, cheapest and what will probably fix this problem is to get new orings and pull the injectors. Bet you'll find one (or multiple if it's really using that much oil) bad seals.

if the oil is going past the internal orings it would be burnt, not in the fuel. One of the external orings must have been damaged or somehow got damaged upon intstall IMO. It's a crappy situation for you my friend. A lot of work to do again.

Yep, I'd pull the sticks and look at the o-rings. Maybe one of them rolled when you reassembled it. If a cup was bad and the oil was leaking past the o-rings I think you'll see evidence of that on the o-rings themselves. 3000 PSI oil flowing past a Viton o-ring has got to leave a mark. My guess is that it would cut and erode the o-ring.

If they all look good, then yep. I'd box 'em up and send them to Rosewood. There has to be something amiss with one or more of them internally. That's the only place it can be getting into the fuel.

Not completely true, back when my o rings went bad my bowl was crystal clear with a light coating on the bowl surface(clean oil though), and filter slightly grey, not near as bad as I have seen some. Truck was eating 8 qts of oil in 35 miles. No smoke, no wet pipe, just shot injector orings.... upgraded the injectors at that point.

I agree, most likely something happened to an external o-ring. Even the best mechanics can make a mistake on occasion or something could've been wrong with the o-ring out of the package. Stuff happens.

Who says vaseline effects them? I used 50/50 vaseline and oil for lubeing up the O rings.

guys listen,and im not tryin to be a d1ck.....THE INJECTORS HAVE BEEN PULLED 3 TIMEZ....i too thought i tore 1 going in.....NO.

Ill say it again. Its not the o-rings fellas. Not the turbo,and not the oil cooler. Its gettin in the fuel....PERIOD. lets look at the anatomy of an injector. Theres a poppet valve at the top thats pulled on by the sillynoid,letting oil flow. At the bottom,plunger and barrel. Think of it like an internal engine. Theres the intensifier piston follow by the barrel. HOW DOES OIL GET FROM THE POPPET TO THE BARREL? im not jim,and i really dont wanna bother him with this. I bother him enough. And besides,this truck belongs to a cheap basterd. He aint gonna buy from jim.
Whats between the poppet and plunger/barrel. Ill scoure the net. Any1 wanna help. Pls post your findings. Again not being a d1ck. And a huge thanx guys
