I have a 1994.5. I got the injector O rings fixed. That was not the problem. Oil is still in my fuel filter housing. Do I need to check my Cylinder Heads?

I still go through way to much oil.

What is next for me to look at?

 

who did the orings? is oil getting into the coolant? is it leaking anywhere?

 

No oil in coolant and no leaks.

 

Is it a powerstroke. Could your turbo is bad the bearings go bad an oil goes in to your exhaust. It will use a lot off oil like your describing.

 

i bet an oring got messed up on install.

 

beat me back to it on the pedistal oring or damaged injector oring going back in.

 

you said that you have oil in your fuel filter so it could be a head or injector cup, or like others have said injector o-ring damaged going in. was it just one injector the o-rings were done on or all 8?

 

I wouldn't think its a pedestal o-ring, since the filters turning black. More than likely a pinched injector o-ring or cracked injector cup. 6.5 quarts a week seems like an awful lot for just an o-ring. Maybe they forgot to install one?

 

The o-ring and injectors where done right by a shop.
The turbo is not making any noise like the bearings going bad.
Please more!

 

you can see the oil in the filter housing?

 

yes, I can see the oil in the filter.

 

One off three things have to be happening. You have to have a leak. Its being burned internally or its in the coolant. Any smoke from your truck at all. Have somebody follow you while you drive downthe road. Just a thought. How many miles on the beast.. Id look at the turbo a friend off mine was taking a lot off oil it was the turbo. There was no exrordinary noise to speak off Good Luck My guess its the trubo with excessive oil usage.

 

if theres oil in the filter i would say the shop that did the orings gets to try again.....

it dosnt take a whole lot to damage one of thoose orings while putting them on an injector or screw them up putting them back in the cup.
i install my orings under oil then let them sit for an hour to let the orings go back to there natural state before install then coat the cup heavily with oil before install. more oil the better.

if it was pedistal orings you will see some blue smoke out the tail pipe but mostly with that much oil it will be coming out the exaust big time. the turbo can function fine and still have the pedistal leaking.


another consideration would be blowby forcing oil into the intake. it would have to be pretty severe for that much oil. you can pull off your intake boot and see the venturi where the vent goes into the intake and see how much goes in. should just be some light smoke. are you getting any oil smoke coming out the dipstick tube? how does the truck run otherwise???
if you have a split injector cup you will be pressurizing the cooling system and be getting oil and fuel into the coolant.

 

I agree. The middle o-ring on the injector is the oil/fuel o-ring. I don't see how an injector cup could pass oil into the fuel filter.

 

I have a 95 and smoke comes out of the oil dipstick like a chimney, what does that mean.

Thanks
