are these motors a nightmare on spark plugs breaking on trying to replace ???? i have read all kinds of posts and well i have come across a friend who wants his plugs replaced and when i lifted the hood i was like well where the heck are the plug wires and upon yahooin the location i came across a terrifying read and want to know if i should realy procede cause they are the original plugs never been changed and there is 123,000 plus miles on them...l iam pretty savy as a mechanic but i dont want to get into a whole mess of breaking things off and having to buy special tools to remove them if they do break.... also can someone point me in a direction of a specific tsb so i may print it out and take with me to a local mechanic or the ford mechanic please thanks....

 

Welcome to FTE.
I moved your post form the 3.8/4.2 forum to the 4.6/5.4 forum. Somebody should chime in with input.
Glad to have you here at FTE.

 

No the 2V modulars do not break plugs, they can however spit them out. There are two worlds of thought on making that not happen. One is to change them every 60K and make sure you use anti seize and torque them properly, usually in the 17ft-lb range. The other is to use no anti seize and torque them to 28ft-lbs.
