V10 Plugs - preventative replcement?

I do not want to hijack JaySVX thread showing a repair with a helicol insert so I am starting a new thread.

https://www.ford-trucks.com/forums/1...-pictures.html

My V10 is sitting at 96k, it's my understanding that I should start worrying as the plugs start popping at the 100k range. I have the 2000 model year.

Should plugs be replaced as a preventative measure? Is there anything thing I can do now to make sure the do not fail me on the road? We typically only use the EX for long trips or family outings. Next summer we will be pulling our TT as well.

I should have noted, I have 260k on my v10.

The issue isn't that it's not strong enough, it often comes with improper re-torquing, then they work their way out and eventually blow out taking threads with them, because there's only 4 threads to begin with.

I drove 100 miles home on 9 cylinders. I didn't disconnect the injector, just the coil. If you disconnect the injector, the computer knows it and it won't run well and will shake all over. With it open and the injector plugged in, it's just a miss, and is barely noticeable other than the noise. Yes you have some gas escaping, but as long as there's no spark, it's not under pressure and surrounded with a lot of air, it should be fine. The gas in the cylinder burns almost instantly. It's the compression that causes the violent explosion.

Jaysvx, just curious, when was the last time that plug was out of yours prior to the launch? Some say you can do them wrong, too often, or not enough. I think it just happens sometimes even in perfect scenarios.

However, I do use the silver anti seize and a torque wrench when doing any triton plug, revised head or not. Also not a bad idea to check them a few thousand miles later to ensure none got loose. Haven't had that happen to me yet though. I just did my 05 plugs at around 112k miles and they were tired. IMHO they need done at 100k. Also a good time to replace the boots and springs on the coils.

The plugs had about 6-7k on them, got all new plugs and coils about this time last year. I don't think there's a 100% tell on what causes it, sometimes you just get unlucky. I'm no mechanic, but I'm pretty handy. I snug my spark plugs by feel and I've never had an issue before now. Some people say 11-14lb, some say 25-30lb, the magic number is probably somewhere in that range, and a little bit different for just about every vehicle.

I would absolutely change the plugs as preventative maintenance! Make sure you use anti-seize on the threads and die-electric grease on the boots, and replace any worn or cracked boots, and make sure of the torque! There is a great thread I believe in the tech folder. I have done mine four times and have it down to about two hours total.

Any plug should be pulled and replaced at 50K miles. It`s just smart preventative maint.

I hear adding an o-ring to your boots help with moisture as well.

Has nothing to do w old/new plugs.
It has everything to do with the proper torque procedure when new plugs are inserted. If they didn't come out for 96K, they won't anytime soon.
If you change them (which you should around 100k), they COULD come out in 5K IF not torqued correctly.

I'm trying to find the folder you mentioned with the thread. Any idea where it is?

Don't quote me, but I believe Ford specifies 100k as these are a platinum plug.

I did all of this above when purchased my 99 V10 with 126k now at 147k with out issue.

This is my plan, I think 50k is plenty long for these engines and plugs. Should also take me at least another 4 years to get there though.

OP- when you order your plugs I would stick with Motorcraft parts. Also you may want to order a coil to have as a spare. I had one go out on me after the plug change.
