Spark Plug Question

[tcam]

Do I use Anti-Sieze or not when replacing the plugs? The manual says to use it, but someone once said in a previous post that using anit-sieze just disrupts the ground to the plugs and not to use it. so which way should it be done?

Go by the book, much safer that way.

I haven't used it when I have checked or changed my plugs. Which reminds me, I was wanting to check them again after I took off that Ingition Amp for wear due to the increased spark energy. That is something you will want to check more often with the amp, Tyler.

I suppose it is ok to go without it as long as I change the plugs fairly soon. So, Brian, I guess I should be fine to just go without it, since u say I should change the plugs more often now.thanks for the feedback

Let the head cool before removing plugs. Aluminum threads can easily be destroyed if plugs are removed while still hot, especially if no anti-sieze has been used.

That is a given.

You know, I can't tell you if the Vibe 1.8l head is aluminum or cast iron... never bothered to check. However, my other car definitely has aluminum heads. That engine produces an incredible amount of heat, so in order to prevent seized plugs in the head I use anti-seize on the plug threads...never had a ground problem, ever. Can't see it using it doing any harm....be careful and start the plug by hand to prevent cross threading the soft aluminum.

I keep changin my mind to use anti-sieze or not, but I'm now going to use it, and stick with that decision. lol

I have been changing spark plugs for 16 years and have never once used anti-seize on them. I have never had a problem with a bad ground or being able to remove the spark plugs. Just tighten then the right way--not too tight, not too loose.I know 2 ASE certified mechanics who do use it, though. Take that for what it's worth.

I suspect that antisieze is recommended because the plugs are recommended for 100K mi. Lots of time for some corrosion to stick em tight. If you're checking or changing every 30K or so, you probably don't need it but it couldn't hurt. I really liked the the Denso IK20 in mine.

[Digger]

I would use it. Aluminum and steel chemically react with one an other to form a welding corrosion. Did you ever have to pound a wheel off after 300 mile. The Aluminum rim bonded with the steel hub.

[tcam]

Alright, it seems to me that I would probably be fine either way, but using anit-sieze is just simply the safer way to go. I don't wanna take any risks of having the plug get jammed in the head, so I think I'll spend a few extra minutes and use the anit-sieze

I'm pretty sure it would be made not to interfere.

[Atomicpunk]

Like Digger said, aluminium and steel react with each other and WILL seize together. If you can find it use the high temperature nickel anti-seize for spark plugs and exhaust bolts. Also, anti-seize has metal particles in it, so I can't see it causing a bad ground.

[tcam]

yeah, I went ahead and got the anti-sieze, and I was actually trying to change the plugs today when I ran into a problem. The socket that I was trying to use was too short and too narrow to even fit over the plug. so I need to run out to a hardware store tomorrow and find a better fitting socket.

[DopeVibeGT]

Definitely use the anti-sieze. I didnt use it one time before on an engine, and it was a pain to get the plugs out after only 24K miles, not to mention scary when it didnt feel right.

[JohnC]

I use anti-sieze on just about every nut/bolt (unless i am using loc-tite). It also helps to get an accurate torque value. Why would you not use it?

uh that reminds me i gotta do my plugs too.....

[northvibe]

just ran up to 47k today...well last night, so im going to oil change, spark plug change and add some injector cleaner today
