Plug Torque

I was at my Ford Dealer today & asked the Service Desk Guy(not a mechanic), about re-torqing plugs and he said no one here gets it done and he's never seen a blown plug come in yet and he's been working there for quite some time. I know it has happened, but I'm wondering about the frequency and hoping this whole issue is blown out of proportion.

I think it boils down to some guy at some point didn't know how to work on his truck (PO maybe?) and was used to torque'n the dog p**s out of everybolt he could get his hands on "like my old tree hundy six-not that damn luminum junk" Lots of people don't ever bother with torque values. 1st tuneup on my 76 (360) I had to use a freakin impact gun on the plugs after soaking them for 2 days because they were so tight!

If you will notice, when most everyone in the V10 forum talks about this we say "use just enough to coat the threads". We never say anything about coating the bearing surface. It's not the extra lubrication we're talking about, but the extra protection against oxidation. Everyone knows if you cake any kind of lube on threads to the point it gets smeared on the bearing surface that the torque values change up to 20%.
The lube (grease, etc) in anti-seize goes away after the engine heats up and the soft metal particles remain, smearing over the mating surface of the threads to fill in the imperfections. This prevents contact between atoms of the dissimilar metals under extreme pressure to oxidize.
No, I didn't stay at a Holiday Inn Express last night....

So lets say the number is one million and that 1000 engines blew out a plug so 1000/1000000 =0.001 or .1% not a whole lot I'll bet there were breakdowns in other catagories that well exceeded 0.1% I guess all we're doing here is try to find a reason and to prevent it happening to ourselves.

Of concern to me is the type of anti seize to use. My concern being that during the warmup and different expansion coefficient of the metals (steel and Aluminum) that the particles would be carbonized leading to future problems. (seizing and destruction of the aluminum threads)
My concern is founded in work related experience with products called Copper slip and Alum slip. Both of these were a disaster, causing the threads of the temprature measuring probes to seize to their mating bottles. My instruction to our lads was to use teflon tape instead which was not allowed but none the less very successful. However teflon tape would be a disaster on the spark plugs.
So I guess my question is what soft metals are in the anti seize to be used?

Yes I did notice and that the emphasis was on "just enough"

I wish there was a tech article just for Ford Triton engines on this...
To answer your question about the residue left behind after installing anti-seize to the plug threads - That compound that is deposited, which is soft metals, either aluminum or nickel, will prevent the two surfaces from "welding" or "binding" together. Without it, all you have is bare metal to metal which will "coke" because of oxidation and you will have problems.
As said in many posts, the best is the high temp anti-seize. I use the aluminum, but some swear by the nickel. I have never considered copper, but only because I've never used it except on similar mating surfaces.
