Unhappy Disappearing oil

Well I have another issue. Not sure if it is self inflicted. I recently had all 8 fuel injectors replaced due to stiction, poor gas mileage and no hot start.

Well now I am losing oil but do not have any visible oil leaks. We used rebuilt injectors from the Ford dealership.

The truck starts up and has been running great. But anytime it sits for a bit on start up it blow out a little bit of white smoke which then immediately goes away.

I am wondering if maybe one or more of the orings on the injectors were damaged during installation. We used plenty of grease when installing and was sure to not bind up the injectors while tightening.

I sure don't want to tear everything back down but I need to figure out where the oil is going. I can say that prior to doing the injectors I was not losing oil.

Could it be from the turbo? CCV? Something else I could be missing?

So not digging all these issues.

Thanks for the information...

Re: Disappearing oil

I'd start by checking the CCV and the turbo. Pull the down pipe off and see if its wet with oil residue.

The only thing i can think of is that you could have pinched an O ring, but i would think it would be smoking blue from the oil mixing with the fuel.

How much oil are you losing? White smoke is either fuel or coolant, not oil.

I assume no knocking noises (fuel knock)?

Re: Disappearing oil

hmm, sounds like maybe you got an issue with the o rings sealing??? did you change injector cups too?

Re: Disappearing oil

I am losing maybe a quart a week. I am not 100% sure on that just yet. Is the down pipe the one that goes to the intercooler? If yes then I do see quite a bit of oil in it. Also quite a bit of oil at the turbo inlet from the air filter where the CCV hose connects. Not sure what fuel knock is. I just replaced the entire injector. Did not touch any cups

Re: Disappearing oil

So that equals turbo seals?

IF there is oil in your dowpipe (big exhaust pipe coming off the back of your turbo).

I'd think if you damaged Orings, you'd have some running/starting issues.

Re: Disappearing oil

is there any oil making it into your coolant? only places oil can go is on the ground , into the coolant , or be burnt through turbo seals or injector o rings or other cracks / damage.

If it was a pinched O ring I would assume it be not running quite right.

Re: Disappearing oil

So I pulled the EGR valve delete cap off the intake and there appears to be quite a bit of oil in the intake. I think I have excessive oil coming through the CCV pipe into the turbo and then into the intake and burned off
