Strange Question
My son has my older 02 Expedition with a 4.6ltr. He went to change the spark plugs and one of the plugs has a yellow almost watery substance in the spark plug hole.
I asked him to smell and tast it to see if it was anti freez or gas, he said neither.
So my question is Do the individual coil packs have any kind of liquid in them? Like oil, or some kind of cooling liquid?
Or where would the liquid come from?
I'm trying to help him do this via the phone due to him being in Washington for school and I in Ventura, CA
Thanks,
Mike

It isn't from the coil. There are lots of reports here about coolant accumulating in some of the plug wells. I am not sure how or why but if you wait a bit I am sure someone who has experienced this will chime in.

FYI, the COPs are filled with hardened resin, not liquid or oil.

Long-life anti-freeze is yellow and doesn't smell or taste like normal green anti-freeze. The heater hoses run over cylinders 3 and 4 (back two passenger side). If the fluid was in either of these plug wells then it could just be a heater hose leak. Some have reported a leaking heater hose filling the plug wells back there with anti-freeze.

Thanks, for the info. I thought they were some kind of resin, but the truck is not here.
That sucks that the anti freeze leaks and causes the short. I will pass it on to him.
Thanks again.

It is covered in ice and mud, how would this get into the cylinder or around the threads of the plug?
I am at a loss

I couldn't make the picture any larger but are you sure that junk was in the cylinder? The plug sits down in a well that was filled with the mystery liquid and presumably some oil and dirt residue built up over time. When he removed the plug it had to be screwed out through the muck, which stuck to the plug. From what I can see the tip looks fairly normal.
I think the dirt/ice was in the plug well and got on the plug during removal.

Hi Big Greenie,
Sorry for the delayed response, yes you are correct that was not in the cylinder but down in the poorly designed plug socket.
My son keeps finding a white liquid around the base of the coil under the boot on #'s 2 and 3. Not a lot but residue and I don't know what it could be. He changed out the heater hoses and it doesn't seem to be leaking into the plug hole.
I don't know what to tell him.
He did get all the plugs replaced and found the place he had taken it when he first moved up to Washington did not change two plugs, so he had 6 plugs with 60,000 on them and two with 120,000. I can't believe some places.
Live and learn, but he changed them all and the truck was still running rough, and gave him a code P030 or something like that. It said #1 was missfiring, I told him to get another plug and replace it, it could be bad. That fixed it and he is off and running again.
He said to say " THANKS to ALL!" who helped us figure this out.
This web site is great with great people who are thankfully here helping each other.
Thanks again.
Mike

Just curious but was a thermostat change recently done. I had a small issues with my #5 when I didnt drain the coolant far enough and when I took the TS housing off, antifreeze went down the hole(#5).

No nothing was done in regards to the cooling system. The truck started running really rough and had no power and keept giving us the wrong codes stating the left bank was running lean. What had happened it a bad judgment call on my part for taking it to Jiffy Lube and they said they could do a fuel management check and a plug change. Well they did neither. I marked the fuel filter with a sharpe marker and the mark was still there as well as two of the original plugs were still in it. What a bunch of monkeys.
My son has the truck and changed all the plugs (that is how we found it) and now it runs great. No prooblems with the coolant any more. I don't know if that was a jiffy lube thing trying to get us to keep coming back to do more work or what.
