First 3 came out no problem. Number 4 turned like it was stripped. Pulled out the top with needle nose and the bottom part stayed in. Next 4 came out perfect. My buddy went to grab the Lisle tool so hopefully it works. 66k miles. Pics to come.

 

The Lisle should work for you.

 

Lisle worked perfect. All back in and running perfect. Fixed the miss I had. I'll post pics later tonight. Plugs looked pretty rough and only had 66k miles on them

 

Did you follow the TSB, run SeaFoam and/or Techron, or your own variance of these methods?

 

Broke them loose with a ratchet with engine warm. Soaked them with Chem Tool for an hour during lunch. Came back with impact wrench with no problems. Couldn't use impact wrench on back two and the back driver side was the only one that broke. It's a PITA to get with tool. Impact wrench is the way to go. I dont think soaking them had much benefit IMHO.

 

It seems as if the impact wrench gives good results from what I have seen here! I think that it is the constant presure that the wrench provides to work the plugs loose, & break away any carbon once the plug starts spinning......

 

I agree. When i did mine i thought the same thing.
All 8 of mine came out but they gave a good fight and squealed like a pig all the way out.

 

for those that used the impact, what sort of attachments did you use? my friend has a cordless impact that accepts hex shank tools, but i seriously doubt i'll find any sort of attachments that will let me use the extensions, sockets and universals that i'll need.

 

What did you use for the replacement plugs ??

 

There are hex drive to 1/4 in. bits available for those type of impacts, then you could use adapters up to 3/8. Should be able to get one at a hardware store of Home Depot/Lowes. I have an 18V Dewalt with that drive that I am going to try. I don't know if that will have the torque required or not as I haven't done any plugs yet. But if you can get the adapter its worth a shot unless someone else has tried with less than stellar results. Just thought I would throw that in there.

I replaced them with the revised plug Motorcraft SP515 from the original SP507. Here are the pics.......



You can see they look pretty bad for 66K miles. But I'm glad only one broke and my misfire is gone. Feels like new again.

 

 

'Milwaukee Tools' has a set of drivers that has a 3/8" square drive in it at Home Depot, don't know if it is sold separately as a single driver though.

 

I used a Dewalt cordless impact and a 1/4'' hex to 3/8'' socket on my plugs.
I started with a hot motor, and hit the trigger in the forward then reverse and didn't stop till i felt the plug spin freely. The back two i had to break loose with a ratchet then put the impact on them, and they came out fine, i didn't have one plug break.
I had 104k on my truck, so i would recommend the impact meathod.

 

I have this electric impact you think this will work or is it to big? Also please explain your procedure to removing them with a impact thanks
