5.4L 3V spark plug change question
#31
The TSB covers 04-05 F150, 05 Super duty, Expedition, Navigator with 5.4L 3V engines.
The procedure is: warm the engine up till it's warm to the touch, remove the COP's, blow out the hole and surounding valve cover area to remove dirt, break the plugs loose 1/8th of a turn, spray penetrating oil (prefirably Kroil brand) to fill the well to the top of the jamb nut of the spark plug, let sit for 5-10 minutes (my experiance is longer is better) Then turn the spark plug out.
If you do break a spark plug off and just the ground shield is left the Ford tool for this is 100% in removing it.

I was also hoping to avoid problems down the road so I just finished re-installing my plugs today on my 2005 SC with 25k miles. Longer is better with the soak time of the penetrating oil, I waited a min of 30 mins (didn't break any plugs), applied a film of nickel anti-sieze, and torqued to 25 ft-lbs. I plan to remove again at 50k miles and I'll see if the anti-sieze makes a difference. This is a job requiring patience...

Jeff,
Did you move the PCM case to do the 2 rear plugs on the passenger side?
I talked to a couple guys that moved the PCM, not disconnect - just moved aside, and they said those 2 plugs were an easy straight shot.

The plugs didn't look too bad. But it looks like it doesn't take much to bind them...it's a tight fit, that's why I'll be looking at them again in about 25k more miles. I didn't think of it but I should have taken a picture.
I did remove the box and it's mounting bracket to get the 2 rear plugs on the passenger side...with it out of the way the passenger side is easy.
I can't believe Ford has another issue with spark plugs...I read that MY2006 and MY2007 have anti-sieze applied at the factory to solve this issue, anyone know if this is true?
