A small amount of carbon build up is normal from all of the intakes I've had off. As far as your oil film goes, have you changed the pcv valve as well as the screen that seats underneath the pcv valve?

Sorry, kind of hard to tell. Your sig doesn't mention a blower, so that's not it. Have you removed the baffle in your valve cover? Maybe it's getting sucked up the vacuum tube from the filler neck to the throttle body. Otherwise the only thing that comes to mind is the pcv and screen since you didn't mention whether or not the car ran and drove normally so I'm assuming it does.

Yeah no blower, although id like one I didnt remove the baffle ,but I had to hammer it flat to clear the rockers. It runs fine, just a little rich. I guess the first place to start would be the valve and screen, and then go from there.

That orangish color looks like when mine was leaking coolant into the intake.

pcv is sucking it into the intake. I doubt doing a new screen and pcv will solve your problem. There has yet to be a good way to stop oil from getting in our intakes via pcv valve. In my opinion, it was a bad design by ford.

yeah i think its doing that too. The throttle body is leaking some into it. I always thought you used gasket sealer on the gasket between the tb and egr spacer, but recently found out your not supposed to. I guess thats why mines leaking.

I bypassed it and put on new gaskets. I'd like to do away with the egr all together.

Why? There is no performance gain by removing it. Since it only operates at part thottle.

Anyways, it sounds like it's coming from the PCV, there really isn't a way to fix it, unless you put in some kind of oil separator between the intake and PCV....

Keep in mind that the egr valve is also dumping exhaust gas into the intake at cruise/part throttle. Exhaust has water vapor in it, unburned hydrocarbons, and makes quite a mess in the intake (think of the inside of your exhaust pipe) - add that to the oil vapor that comes in through the pcv and over a long period of time (years) you can get quite a mess inside the intake - not uncommon.
