On a TSB, the car has to show the problem to be fixed. It's hard to demonstrate the problem with something like this. IF Ford were to do anything about this, it'd have to be a recall. One heck of a recall, at that.
Why cant we just leave the part that seperates from the electrode in and just put in a new electrode? That is if the electrode doesn't break off in the head.
This would not be possible
Leaving the old ground shield electrode that's stuck in the head, and replacing only the remaining portion from a new spark plug will definitely cause multiple problems:why not? the electrode is what needs to be replaced. so if the little tip seperates and is stuck in the head why not just replace the eletrode? just wondering. please explain
I have replaced hundreds of plugs when they are hot and never seen that. Must be a Ford thing.You better be careful removing plugs out of aluminum cylinder heads when they are hot. The threads could come right out with the plugs.
Hope this doesn't sound like a dumb question, but what is the difference between our 3v aluminum heads, over the 2v-4v aluminum heads that were used in the 99-04 SN-95 models. As the threads were still aluminum, weren't they ?
If I'm also not mistaken, didn't the 99-04 models use 2 piece designed plugs as well.

Because the Lady in the customers lounge with the three hyper kids doesn't want to be there all day.I don't think it's necessarily a Ford thing. I've always read and been told to use care when dealing with aluminum heads. Changing the plugs when the heads are cold yields the best chance that you won't strip or otherwise mess up the threads.
Can you get away with doing a plug change when the heads are hot? Probably. But why risk it?

Local schucks said they don't know when they will get the 7989, and napa said its on national backorder. I called Championsparkplugs.com, they say they have 130 in stock with more on order. I think I'll eat the cost of new 1-piece plugs rather than changing the OE out every 15k miles (which is what my dealer recommended to get them out before they have the opportunity to sieze up and break off in the heads) or waiting until 100k and then being stuck with a $700 repair bill.
