I am replacing the spark plugs in my 2012 Ecoboost and am having a hard time getting the coil packs off. I got the first four off but they were all stuck on pretty tight. I can't get the last two (driver side closest to firewall) to come free. Any suggestions on how to get them loose?

Thanks

Screw is removed and they wont come loose? Did you try twisting/wiggling them a little?

Was there a lot of corrosion on the others?

I had the same issue when I was replacing the plugs. spray a little PB blaster behind the highest point of the coil pack so it can drain down the valve cover and get to the rubber part. wait a bit, wiggle, spray again, wait, then try and remove. look at the ones you already removed and see where the weak points are. you can use a screwdriver (WIDE head) to help pry, but if you do it wrong you will crack part of the landing. looking at the removed ones will show you what i mean.

Mine only had 20k on it but a couple of mine were tough also, I just got my finger's under the top an started twisting with light pressure an they popped off once i broke the suction.

I could not get enough leverage to get the back two off either. I looped a piece of 12 guage wire around the neck and pulled like a ****. They came right off doing it this way. I wouldn't try and pry them. They are really easy to crack.

Hell I can't get one of my screws out that holds the coil pack. It's been in there for a while now and I know it needs to be re gapped. I really need new plugs. The piece that's in the valve cover that you screw into is loose and it just spins and spins. I've tried everything I know to get it out and it's not budging.

Cut it pff with a Dremil tool ?

Well I could cut the bolt with a Dremel and get the coil and plug out but then I couldn't tighten it down again. The only thing I know to do is replace the whole valve cover.

If u cut off the head off, remove the cop and then pull the screw out, U can then drill an instal threads back with new screw. Perhaps a friend can help.

Cut the bolt with a Dremel and after you replace the plug pull the part out of the valve cover with a needlenose and degrease it thoroughly and then use JB weld to epoxy it back in place. Just be careful how much JB you get in there and don't get any on the threads. Then when you replace the bolt put just a little silicone grease on the threads and don't tighten the crap out of it. Make sure you let the JB cure well before you put it back together.
