The TSB applies to 2004 5.4l. Does this mean that I have nothing to worry about with my 2005? Was there a change to the clearance or a plug material spec change in 2005 that truly fixes this problem?
Thanks

Then they turn around and bash on ford. if you want a vortec there is tons of them out there, by all means knock your self out.

I read a very good article on this plug problem and the reason Ford doesnt stand behind them is they can't afford to, which of course is no excuse. Their already near financial collapse so to avoid the expense of admitting their mistake they prefer to blame the spark plug LOL. I would like to know what they were trying to achieve with this design that led to this problem-ws it suppose to give better gas mileage?burn? what?

Thanks ohboy44. Where did you find that info?
Since it is not clear that the problem has been completely isolated, how do we know that replacement plugs won't have the same problem? I don't mind changing my plugs out if it truly solves the problem.
thanks

Ted928 I have access to Ford online service info.
I wish I could tell you more about this issue but I could loose my job.
I will tell you it's a good idea to take the plugs out using the TSB and let the penetrating oil soak in longer then 10 minutes.

The problems are not safety related so no recall is required.

The plug is a very different design, they moved the threads to the middle of the plug, so the part of the plug that goes into the chamber could have a much smaller diameter, to make room for the 3 valves. Its a whole new design made just for this engine, and therefore had no history, so ford couldnt have known it would be an issue. Hindsight is 20/20, the design of the plug really cant be altered much, but perhaps some antisieze or maybe an impregnated bronze sleeve could work to help it from sticking.

there is no reason not to use it, but not only on the threads, i would apply a VERY THIN LAYER on the part of the plugs that extends through the cylinder head. not on the top, but the sides.
