Sorry... I was in a hurry when I posted this last night.... I went with the Bosch +2 because I have been through three sets of motorcraft in the last 15,000 miles... If these go bad I will replace them something else.....

The problem I am having is the brass bolt holding the ignition coil is just turning in the fitting (It seems like it has seized for some unknown reason)and won't come out. I have tried using a little bit of leverage but was unsuccessful if anyone has any ideas how to get it out I would GREATLY appreciate it.
(I would post a picture but do not know how...)


2000 F150 Lariat no upgrades yet 76,000 miles... Have no problems changing plugs before....

When I've replaced them I have used the di-electric grease and anti seize.

 

You'll be sorry....

Why are you blaming the plugs on not being able to get a coil off? Did you use dielectric grease on the inside of the coils upon installation onto the new plugs? Going back with Bosch plugs will only make things worse.

 

I'll second projectSHO89's comments...

I changed to bosch platinum plugs when I changed mine because the store didn't have the motorcrafts in stock. BIG mistake - I got hesitation, misfiring, and the occasional backfire after changing the plugs.

If you want to "upgrade" your plugs, I'd reccomend NGK iridium plugs. I bought them and have no complaints. Bought them, checked the gap (they were right-on) and installed them. No problems now.

If you're having problems removing a COP coil, just pull harder (assuming you've unbolted it). The coil may come off without the boot, but that's easy enough to grab with a pair of long needle nose pliars.

Good luck

 

I appreciate the advice on the plugs, but unfortunately I have already installed 6 of the 8 plugs. I f the go bad I will use the suggested plugs. The brass bolt holding the coil to the head is just turning inside the fitting. I memory serves me correctly it is another brass fitting inside a rubber groumet which for some reason is not releasing the bolt. When i changed them last I didn't have any problems and used anti seize on the bolt to prevent rusting or possible cross threading. Any advice would be appreciated. Thanks...

 

Have you tried prying up on the coil as you loosen the bolt?

 

BlueOval , Yes I attempted to use leverage but it still will not come loose. I was wondering if anyone else has experienced this problem whilst changing the plugs. If anyone has any other ideas I would appreciate them.

 

Do you have a Dremmel cutter? Its an idea!

 

Thanks for the idea... I thought of that also but was seeing if someone has had this particular problem before. If I use a Dremmel I still have the problem with the bolt and the question I am raising is will I have to replace the whole plastic plenumn covering the engine (since it is one piece) or is there possibly another fix. I am trying to work it out keep y'all advised...

 

Please someone has got to have an idea???????

 

celsius,

The bolt is screwed into a metal insert that is set into the intake manifold, it is held there by little knurled marks on the insert. So this is just spinning in the plastic intake manifold. The only way I see to get the bolt out is to stop that insert from spinning, Could you get a vise grip on the plastic under the bolt head and put a little squeeze on the insert area. The insert is proably short so there may not be enough room to squeeze it.

Good luck! Intake manifolds are big $ compaired to spark plugs!

 

Thought of something else that may work, try clamping a pair of vise grips on the bolt head and pull up along with the coil, maybe if your lucky it will pull the insert out of the intake manifold.

Once out you can screw the insert off the bolt and ( JB weld, glue or what ever) the insert back into place.

Remember us very little troque on those bolts! It's not like they are holding the Brooklyn bridge together, just that litte 1/2 pound coil from jumping up.

Again good luck!

Help!
I've got the same problem with a stuck COP bolt. I was going to check my plugs this afternoon and wouldn't you know it, the COP bolt on cylinder #1 just spins. I've read this thread but it didn't really help me a lot. Did anyone have success solving this problem?

Also, is the truck okay to drive in this condition? I started it up and checked around under the hood while it was running and it didn't seem to show any problem, but I am a little concerned/paranoid.

Still working on my problem.... the replacement plenum is approximately 585.00 and have found no viable solution. I have been driving the truck with the stuck bolt for a good while now without any difficulty BUT eventually I am going to solve this issue. Let me know if you get it corrected... I've talked to several auto repair shops and all they want is an obscene amount of money.

 

Use a dremel to cut the head off the bolt.

You will be able to remove the COP and the remains of the bolt will be sticking out of the stud.

Use a block (trim to fit) of wood as a prying platform and prey out the bolt and anchor. (Vice Grips and a Wonder-Pry bar worked for me).

Fill the hole with JB Weld and smooth it out to be drilled after it cures.

Get a helicoil (or simular product) follow the instructions for drilling/tapping new anchor threads. (It is better to go with a slightly smaller diameter bolt - it doesn't need much to hold the COP in place).

Entire process can be performed in a 36 hour period. The actual time working on it will be less time than it takes to change your plugs. The curing time is necessary for the insert to hold in the new material.

Also - stay away from platinum plugs. Go with stock or Iridium.
