I recently changed the plugs in my 06 Lariat with 79K mi.
I followed Lifted5.4Lariat's post on his technique and did not break one spark plug (5.5 hours later but VERY HAPPY and RELIEVED). Patience is key for this job.
Coated the plugs ( Motorcraft SP515 ) with high temp nickel anti-seize and put them in .
My question is when I change the plugs again do I need to soak them and worry about them breaking or can I crank them out with no worries ?
I still have the never used Lisle tool in it's package .
Should I keep it for the next plug change or sell it ?
Anyone changed their plugs a second time with any problems ?

 

I haven't had the pleasure if doing the second plug change myself either. That being said, I think I would err on the side of caution and go with the TSB again. Just being on the safe side......

 

I'm no expert but I think changing them around 50-55k intervals and running some techron every few thousand miles is ample. I run a few bottles during each oil change period. I'm also an **** nut though I'm at 84k and had them changed around 58k. They broke 5 but I've been on top of maintenance like clock work so hopefully the next change is smoother.

 

You should be ok. Dealer did my first chang at around 36k. I recently did my second change at 98k and they came out with no problem whatsoever. I would break them loose with a torque wrench set at 25-28 ft lbs. If they start squeaking, then start following the tsb. If they are quite just keep loosening. When I did mine, I cracked the first plug did not hear any creaks groans so I just kept loosening. It came out no problem. Almost all of the antiseize was gone but there was some residue in the plug seat. Dealer used copper not nickel but it seemed to do the job.
