Just wondering what kind of anti-seize do you use for the spark plug threads (if any at all)? While I was replacing the plugs, I have noticed that the threads were quite rusted. Advise appreciated as always.

 

I used the same kind on the plugs that I use on everything else. Permatex sells it in a gray metal tube. Keep it only on the threads and you should be fine.

 

Definitely put some anti-seize on the threads of the plugs. IIRC there isn't any special anti-seize for plugs only.

 

Hi-temp Permatex anti-seize. I use the copper one with the paintbrush built into the lid. I think there's another one (black?) that's even higher-temp rated. If you use this on every bolt you remove you'll be glad you did if you do a lot of wrenching on the car. Especially in areas where they use a lot of road salt.

 

anyone know y i can't post???

...you just did post



You'll find many opinions on both sides of the argument, whether or not to use it. No manufacturer that I'm aware of has ever used it from the factory, says enough to me. Personally I never use it, and I've never had a problem getting plugs out of those vehicles years later.

 

Yes it's a good thing!

 

Spark plugs come nickel plated on the threads. The nickel shears off and acts like nickel-based anti-seize.

If your threads are in good shape therefore there is no need for anti-seize. But adding it won't hurt.

 

I skip it lest I overtorque. Overrated.

 

Good point!

Nice to know.

 

I do it as a matter of habit. We always had 15+year old hondas that had problems getting the old plugs out because the MF grease monkeys who changed the plugs (before we owned the cars) put them in too tight and the slightest bit of rust/whatever fused them to the threads. Talk about a PITA.

I get the stuff at the counters at Advanced Auto (little gray packets).

 

Whenever i refer to the haynes manual it says to add anti-sieze compound...thats good enough for me. Dont matter what brand u use, jus make sure to get the stuff for use with spark plugs

 

Copper Anti-seize on the threads, dielectric grease on the terminal. Not required, but usually recommended.

 

i use it to me makes it easier when time to replace them

 

With a spark plug it should be torqued using turn of the wrench to compress the crush washer to the correct amount. The only way to overtorque them is to turn the wrench around too much and flatten the washer completely.

Granted that I've never overtorqued a plug due to using anti-seize, I'm generally more conscientious than I used to be regarding torquing and whether or not the spec reflects application of a substance. It just happens to spill over to this. I still contend that it is an overrated and unnecessary step.

 

Using anti-seize is beneficial when your alloy head is hot, as it can allow you to remove a spark plug with some heat in the engine rather than changing spark plugs first thing in the morning on a dead cold motor. Seen a few people strip spark plug threads removing spark plugs on a warm motor.

Another thing is that a blown headgasket can push water up the thread under compression and cause the spark plug to rust in place as well.

I am quite happy to use a small dab of ARP grease, since I usually end up with heaps of that left over on an engine build anyway lol

 

wuh i just put some normal ones... is it gonna bust my engine?

edit - nvm the package(which i threw away) had a picture of spark plugs so i guess it better not blow up my engine.

 

anyone has a write up with pics how to change the plugs for an 05 maxima???

 

Fail.
