Retorque sparkplugs?
So last november i blew a plug on my 02 v10. I bought the timesert kit and an inspection camera to do the job. I put in new motorcraft plugs but did not change the coil boots or springs. Latley my truck will occasionally develop a miss but it seems to only be after it rains or after I wash it. Im thinking some of the boots might be cracked. So I ordered a set of boots and springs. Would it be good to retorque the plugs while Im changing the boots or should i just leave them alone? I did not use antisieze and I torqued them to 20lbs. dry. I dont want to strip anything retorqing. I have a slight ticking noise but i think its the exhaust manifold, I have a few broken on both sides.

It's not worth it to me to not use antiseize on spark plugs.
Almost broke several on my brothers volvo replacing the originals at 120K miles.
It wouldn't be too much more work to pull the plugs, check them and reinstall/torque with antiseize.
Also, I replaced all the boots on my F-250 that had 155K miles. All the boots holes had expanded to 1/2in. The new ones are like 1/4 I think.
They expand and wear out over time with heat.

On my 5.4 V8 plugs I use nickel-based anti-seize and torque the plugs to 23 ft/lbs---its worked great to this point. There's a small controversy about anti-seize but for me I'll continued using it.
I use an NAPA/Belden boot p/n 702418 for like $5 each---keep a few around just in case. Any signs they're not 100% and I change 'em---don't need or want the aggravation something so cheap yet important can cause.
Glad you got that sorted out, lesson learned the easy way!

Im going to go ahead and torque the plugs again. I got over 100,000 out of the first set of plugs. Hopefully I get that much out of this set. I feel like if I would have just change the plugs at 100,000 like it is recommended I would never have blown a plug. I pull a 28 ft. travel trailer alot with this truck, in the west. Alot of steep grades. I sometimes worry I might blow another one out in the middle of know where.

You're not doing yourself any favors by letting the plugs go past 50K. I know the specs say they're good for 100K but all over the V10 and V8 modular motor forums 50K is just about the max life.
Once the COP's are outta the way swapping the plugs is half way done anyway---go the distance and improve your MPG's and performance all over again!
