The zabeard method worked great!!! Had 67,000 miles on it.

 

What method might that be?

 

Did you use air or electric? Nice man! That's how I'm going to try to do mine

 

Warm engine and hit them with the 3/8 impact, no lube of any kind

3/8 air impact

 

very nice! best method too! run better>?

 

Runs alittle smoother, I guess but it didn't run bad before, edge is telling me alittle better gas mileage but im not going to believe that until I put another 500 miles on it to be sure lol.

 

Awesome! I still need to do this but I can't afford the down time if I break one.
I'm not sure what to do right other than just keep driving. lol

 

I bought a lisle tool just in case, I got off work was in a bad mood looking for something to do, the plugs where laying there so I popped the hood and went to work. Took about two hours, but there where one or two beer breaks. The back took some creativity moving things and getting the right extensions to get the impact in there. A couple of them took alot of hammer on them with the impact, I had to wait for the compressor to build back up. This impact was rated for like 150ft/lbs. Just a cheap craftsman I paid like $35 for it last year on sale at Christmas time.

 

Ah perfect, I have a cheap kobalt that's rated for 300 I think so that should work perfectly.

 

Ya as long as it smaller cause my kno for sure I couldn't get my 1/2in impact back there and its only an inch or so longer.

 

That's a plus you didn't break any, i'm happy mine won't have this plug issue.

 

WOW, those plugs have a long reach! First time I've seen a GND electrode design like that. Does it have C.O.P. (Coil On Plug)?

 

your suppose to change them that soon??

 

Yes it does

Not really, it's recommended 100,000 miles but they tend to break easier then.

 

Im glad I did them, they where in pretty rough shape and way out of spec. Ford says 100,000 like trent said, but people also say they go 10,000 on an oil change, I would rather do them now, I will probably do them again in 30,000 if I still own the truck lol.

 

This plug problem ended on late 08 models.
late build — brown coil boot, older build have black coil boot.

 

I thought it was the late 07 models?

I plan on doing mine soon, just need to buy the plugs.

 

Check your coil boot, brown is the new type, black older type.

 

Mines an 06 so I know it's black for sure. That's just what I read on f150online

 

I have a '98 with the 4.6. I've had since new, 77K, runs good but I should change the plugs. Did the 4.6 motors have the plug removal problem like the 5.4? any advice? Great job changing the plugs! I had always read that they were easier to get out if the engine is cold, not true? thanks

 

No they don't have the same issue, only the 04-07 5.4s do.

 

thanks, that makes me feel better about changing them out.
