I was changing out my coil covers just testing out a new set i got and i noticed this. Could this cause issues or is it an issue? What can i do to fix it? It looks like rust :puke:

is it rust or burnt oil residue?

Rust on Aluminum heads?

looks like water is getting in there, is the rubber seal around the bottom of the coil cover in place?

Well in that case it could be the same thing that happened to me, the rubber gaskets for the plug ports were bad and oil got in there... if that's the case you'll have to take the valve cover offf

Rust, (corrosion) on Aluminum is white, there is other metal in that area, but not that would cause that much residue. Taste it if it's oil residue you will know. BTW corrosion on copper is green, thus the Statue of Liberty's color.

Dont think that could be it. As u see its the only plug with this "issue"

I know that is a problem on the Lincoln 3.9L DOHC motors, but I havnt hear of it with 4.6Ls

Ok update i tasted it and it is kinda tasteless....
Second the slipperyness is from a clear silicone around the corner where the wires pass through the coil covers bottom left corner.

My guess is where the wires pass thru the notch in the coil covers, you are getting moisture.

Common problem with these covers.

Make sure the coil cover gasket is in pace correctly, and buy some silicone sealer to place around the notch where the wires are.

You should be OK at this point.

Good luck!

I think the o-ring gaskets around the spark plug holes leaking from age is not unusual with 4.6's - at least, it happened to me. Was just one o-ring, caused that plug tube to fill with a couple ounces of oil. Can oil drown a plug like water?

I had a bunch of crap in that same spot. I cleaned it all up, took some Toyota Black (really good silicone, $15 for a small tube) and put it all around where the rubber gasket sits and a lot back where the wires come in and check it every once in a while and clean as can be still.

+1, when I did my cam cover install there was the same residue in one of the cylinders. I used silicone on the coil covers and that seems to cure it.

Exactly. I had the same issue, maybe a little worse as I shorted out a coil, way back when I had the car only about 6 months. Mostly on the passenger side, drivers side was always fine. I've added re-sealing to my normal pm, about twice a year. I use high-temp silicon. Remove the cover, clean out the area where the rubber gasket is (where the wires enter), apply silicon, replace boot, add silicon to top of boot, replace coil cover.

Do this whenever you change your plugs.
