Cylinder 1 Contribution Error, Still. -- Video Included

Long story short, I was getting an "Injector 1 Contribution Error". I replaced the injector with a new one from Ford. Same error came back after about two drives.

Cylinder 1 is the forward most on the passenger side, right?

The only other issue I could think of was maybe a High Pressure Oil leak at the injector? So I took off the valve cover, and ran the engine. Below is a link to the video. There is a bit of oil coming out of the top of each injector, but from what I've read, that's normal right?

I would really appreciate you taking a look at the video, and letting me know if you see anything strange.

Thanks

Thanks. Has anyone ever gotten a bad injector right out of the box from Ford?

Contribution is a inferred calculation by the pcm so this could be a false signal.
Did you make any actual physical tests to verify? IE compression test; check for voltage at the plug in etc.

Unfortunately I don't have a compression tester. I know I need to pick one up. I see harbor freight has some cheap ones, do they actually work on the 6.0's?

I haven't checked voltage, but would like to. Can you tell me how? I did peel back the wire wrap and inspected the wires, they all seemed to be in good shape.

Yes the harbor freight one will work thru the glow plug hole.
As for checking voltage from the ficm you can unplug at the pass thru at the rocker box
The member Southend knows the ohm values of the injectors by heart. Actually I think they are tattoed to the back of one hand LOL He knows a bit of checking injectors.

I'm pretty certain oil coming out from around your oil rail tips is not ok.
Here, check this out. ...... http://www.accuratediesel.com/shop/243.html

Whoa, just checked out the video. ...... that is not ok. Remember at idle your oil rail is seeing about 500-600 psi. Get on the throttle, and you will see upwards of 3000+psi. I think you need to investigate the oil rail nipple orings and maybe the upper orings in the injectors also. There is a kit for those too. Let me see If I can find it. Be back. ........
