Can plugs be regapped?
Plugs had 25k on them so I checked that the were all properly torqued and they all seemed fine. Decided to pop one out to check the color and measure gap and it is .065 from the .055 when I installed them new. I know some expansion is normal but I never to this extent.....considering they are platinum cant I regap them or not?
BTW, I use motorcraft platinums.

Was curious too. FORD's "Normal schedule" for my '98 doesn't even touch spark plugs until replacement at "100,000 MILES" as they'd claimed in the sales brochures.
Of course "motorcraft platinums" can be regapped like any other plug of this design, most get regapping right out of the box. Even exotic platinum electrodes are slowly eroded away, consumed by the arching of millions of miniature lightning bolts. Presumably, adaptive computer abilities actively compensate for normal gap "expansion" allowing FORD's confidence in a 100k replacement schedule. IMO it shouldn't be neccessary to regap the plugs b/c these systems are flexible within limits & designed to adjust themselves for normal wear. I would like to take FORD at their word & see if the original plugs will go 100k w/o misfiring.
Considering all the hysteria over reports of spark plugs stripping threads in the early aluminum heads, then blowing out hard enough to damage coils, fuel components & even dent the hood-I don't plan on tempting fate & messing with them unless I have to. How's it going for those fighting b/c warranty didn't pay?
All I've done was use compressed air to blast out any debris & dribble some PB Blaster down in the spark plug pits. Course I've only just passed 10k.

Ford (up here in Canuck land) recommends 50000kms check the torque on the plugs due to the infamous "spark plug ejection" problems inherent with these engines as preventative maintenace. Although there is a small percentage of spitting plugs they felt it was necessary due to the expense envolved with warranty claims......this was right from the horses mouth of the service dept. at Universal Ford in Calgary Alberta.
Funny how Ford is just recently wising up to an apparent design flaw....except they make the same mistake in the new 3V tritons where the plugs sieze into the heads.
