Every last plug broke on take out attempt. I have heard of this happening but not to all of them at the same time. The worst part is on one, the broken piece(s) went into the cylinder, and they later removed the intake to try and get it out, but no luck.
SO.. my next move is to have it towed from their shop to the Ford dealer, who's tech guys are pretty experienced with this mess. Should have gone there in the first place but hind sight is 20 20.
I know there was a class action suit about this stuff against Ford but seems like it never went anywhere.

The 5.4's have lots of issues..especially the 4 valve ones
The Ford family of motors is known for springing coolant leaks..especially from the right rear of the motor...Cracked intake manifolds & gaskets, freeze plugs, heater core, heater core fittings and hoses.
But that aside the 2 valve model 4.6L are known to go 270K miles
