Good afternoon,
I decided to replace the plugs on my 2006 F150 today. I followed the TSB and broke every one of the right side of the engine. The left side came out fine. The lisle tool worked great on all of the plugs except for the rear one. When I started to extract it the tool seems to slip and strip the metal plug shield out. Now the tool will not grab the shield and I can't get it out. I really don't want to have this taken to the dealer and get charged $2000 for a head removal. Any ideas on how to get this shield out? I appreciate the help.

 

Tried everything, I cranked it with the fuel rail disconnected and nothing. Even tried hooking everything up and starting it with just that one cylinder disconnected, revved it a couple of times and no good. I guess the dealer gets it, I only hope they will have better luck removing it then I did so they don't have to pull the head.

 

try soaking it in the kriol longer

 

It's been soaking since yesterday morning. I tried the tool again, but the threads just won't grip. I am going to have to take it to the dealer and hope they have better luck then I do with their tool or I will have to pay to have the head removed.

 

You could consider building your own puller. I don't remember where I saw it (I think on another forum). Some guy had the same issue. If I recall correctly, He tapped the shield with (I think) a 3/8" x 16 tap (1/2" deep) - inserted a piece of allthread. Then used a socket as a spacer. Then pulled the shield with a nut and washer.

I don't know if this helps - depends on your prowess I guess. Good luck.

I appreciate the help, but I have already set up the appointment to drop it off on wednesday. I might try one more time tomorrow night just to make sure but I don't want to mess up the head.

 

Haven't gotten my tool yet _ BUT - I noticed there is a replacement puller screw available. Lisle LIS 65620 Puller Screw Replacement for (65600) | Lisle
Is it possible the puller got worn pulling the others and just isn't cutting enough to grab the last one?

 

Thats a good question. The threads look used but they should grab. That seems expensive for just the puller screw.

 

Have not done any plugs like this but here's an old trick I've used before in other situations. Depending on the clearances and strength, take a piece of wire or preferably lead solder. Stick it down into the hold to the side then see if the tool will thread in. Sometimes it will take up enough slack that the extractor will bite into the walls. In principle you're narrowing down the hole so the threads will bite into something. If possible, I like to use a length of lead solder as it will do little if any damage if it gets into something by mistake.

Good luck

If you think the threads on the puller are worn. Just take the first few off on a grinder and you should be good to go. Heck, at least it's worth a try. Anything is probably cheaper then a visit to the service department on this one.

 

Did you try calling Lisle? They claim to have a lot of tricks not listed on the instructions and one might just work. There is a help line number on the instructions.

 

Thought I had it with the wire trick, the tool gripped with a small piece of lead solder down there. But it still slipped off. I took it to the dealer today and decided to let them give it a shot. I expected the worst, even priced the cost of head removal. I figured they were going to not even try and just remove the head to get the extra money. However, the service manager called me this afternoon and said they were able to remove it. All said and done cost me $91, I would have to say it was definitely worth it. They are putting my new tires on tomorrow and I will get my truck back with most of my bank account still intact. Thanks for all the help on here.

 

did you buy your lisle kit new? Did anyone of the porcelins break off in the ground electrode?

 

I bought the tool new, only four of the plugs broke off. It was the first four I tried to remove, so I am thinking if I had let them soak a little while longer it would have been fine. I would let them soak overnight before I do it again. We are doing my buddies 06 when he gets back from Afghanistan, now that I know what not to do it should be easy.
