spark plugs + aluminum head + ...neverseize?

[AJMBLAZER]

About to go do the spark plugs in The Tracker. Anyway, I bought the plugs through RockAuto and never thought to pickup one of those little packets of "spark plug goop".
Is regular never seize the same thing?
I've got a pot of NAPA's silver stuff.

never sneeze is fine... just dont get any on the bizness end...

a little goes a long way too.....

 

[AJMBLAZER]

Thanks guys. Light application of never seize on each one and they went right in.

Old plugs were rather white-ish though...runs SO much better now.

Is there any grey tint to those plugs AJ?
They look pretty white=lean.

 

[AJMBLAZER]

Two are a bit grey/tan. Two are pretty much all white on top.

I'm guessing they're the originals at 97,000 miles. No codes and runs better now.

Damn near all FI engines will have white plugs if all is well.

Speakingof antiseize, I have a bottle I have had for well over 10 years. Stuff goes a long way

Especially if you get it on your hands.....Then it goes EveryWhere!

I found some genuine Never Seize in a spray can. I bought it as a joke, figured it would be so messy that you would have to take a bath afterward.

Then, one afternoon, I mislaid my brush can and had to use the spray.

It was great!
A quick spritz in each bolt hole or on each bolt, and you never had to touch the stuff.
I still have the brush can, but I ordered a case of the spray and gave some to all my friends.

The brush can lasts longer, mainly because I don't think you get as much per can, and you will find yourself using it in situations that you would not with the brush, because its so easy.

OK,,, from this thread now i am getting that so far everyone is agreeing that putting this stuff on the spark plugs is fine, and a great idea, BUT i have read in other threads, almost sure it was this board, that it's not that great of an idea, as it supposedly affects the ground contact that the plug is required to make for proper spark function...

SO

which is it

I'm just curious, i don't have aluminum heads, although i think my dads car does. I did not put the stuff on those plugs, i just made sure i didn't over torque them during installation, as i technically do with all plugs.

Well, I imagine that there might be a small amount of insulating going on, but at 50,000+ volts, it would have to be some darn good insulation to make a difference.

However with aluminum heads, where you have aluminum threads that the plugs screw into, its been my experience that its a matter of when, not if, you have to replace the threads in the head if you don't use the goop.

Torque has not much to do with it.
Sooner or later, you will start to remove a plug and feel it start getting tighter and tighter.
Your best move then, is to carefully reseat the plug until you can make arraignments to helicoil, or one of the other methods, the head.

Steel rubbing on aluminum with no lube will gall sooner or later.

Some aluminum head engines have steel inserts from the factory for that very reason.
