Seen a few videos on removing spark plugs with a pneumatic impact gun.

anyone tried this yet?

If so what PSI was the compressor set at? usual or did you have to turn it down some?

 
Sounds like the worst possible tool to use.

Stay tuned for 4.6L 3V owners comments.

a blown engine worth nothing and on an engine stand maybe when you lwant to tear into it to what failed or to teach a son or daughter even then seems to be crossing a line some how

So I did this.

I tried to loosen the plugs by hand but they were locked in place just the way I read they would be.

I borrowed an impact gun and loosened them all. They porcelain chipped and cracked on a few but none of them completely broke in half. The ones that did chip I used a shop vac and a piece of fuel line to suck out the pieces before actually lifting the plug. I did have the broken plug extractor kit on hand if any of the plugs had broken in half. They come right out.

I replaced them with champion platinum tips.

I can't imagine why Ford hasn't asked Motocraft to build plugs that don't crack on the way out. The strange thing is Ford has taught their techs how to extract the broken plugs and not fixed the real problem......

85K on the old plugs. Truck runs nice now.
 
It's best to use a little dab of anti-sieze compound on the plug threads before installing them and then don't over tighten them. Installing and removing sparkplugs in aluminum heads has always been a problem. When you put steel threads (sparkplugs) into aluminum heads they expand and contract at different rates when the engine goes through it's hot and cool down cycles, thus you need anti-seize compound to prevent the plugs from seizing in the heads.
