Changing spark plugs. Book says apply anti seize to threads. Do you do this? If so can i use my anti seize that i put on my muzzleloader breech plug

I can't ever remember putting never seize on a spark plug and I have installed and removed hundreds of them in every nasty environment there is from salt to freezing to baking temp. No problem............

Me neither and I've changed a bunch
i wouldn't use anything on them. Lookup the spark plug manufacturer recommendation. Most quality plugs are coated for ease of removal

I put anti-seize on everything, Including spark plugs. I consider it a time saving measure next time I work on something.

 

[kudidl]

The "original" anti-seize compound and extreme pressure lubricant formulated with copper, graphite, aluminum and other ingredients to protect metal parts against rust, corrosion and seizure up to 1800°F. Fine metallic and graphite particles in special grease protect parts even in high heat, high pressure and corrosive environments. Ford ESE-M12A4-A, Garrett Engine Div. PCS5724, Pratt & Whitney PWA 360523-2 and tested to MIL-A-907
I ain't putting " fine metallic particles" in my engine

It seems like almost everyone recommends anti seize on spark plugs except the plug manufacturer and the vehicle manufacturer.

I don't use it on plugs. NGK doesn't recommend it.

 

[kudidl]

Yeah I saw that on NPK plugs but I guess what's good for one person may not work for another. just can't see me putting that on something that could get into an engine. External parts, exhaust manifold etc yeah but not internal.

 

[Toxic-21]

Most anti seize products are made with ground metallic particles.
I have never, and would not recommend putting it on the plugs.
I do agree, external yes, internal no.

Yah, like these guys said...I aint doing it. Lubricating metal with metal in a motor...ill pass..i think others should too. AntiSeize has ALSO been known to help threads pull. If you DO use it, i suggest using a torque wrench then...cuz greasing or lubing something with threads will make it easier to tighten...and also overtighten and damage threads.

kinda like when ya tighten head bolts on a Cummins, they suggest applying grease on the surface between head bolts and washers so that its easier to accopmlish the recommended torque...which is like over 300 ft-lbs. (which for a ltitle guy like me, its damn near impossible in some situations..lol)

Good point!
The Anti Seize changes the torque spec for bolts as well as the spark plugs. Lubricated or non.

Wagz, you know how to use a cheater pipe right???

Wagz, you know how to use a cheater pipe right???

yup, got a few stuffed in the bumper for the 3/4 drive. For horizontal bolts, the crane comes in handy.. lol work smart, not hard!

 

[berks co hunter]

The given torque spec is for lubed threads
and under the bolt head. If it isnt. The torque
will not be correct. Every manuel says
clean and lubed threads.

I read on NGK's site that they are "self lubricating" in a sense due to the "trivalent" plating which prevents the corrosion that could cause problems as well as acts as a release agent for plug removal. This of course was news to me, but a welcome bit of info!

With that said, when there is a steel spark plug in a aluminum head I am always concerned with the corrosion that can occur between the dissimilar metals. I work in the marine industry and I can tell you that anti-seize is a life saver. However, in thinking about it we all probably change our spark plugs frequently enough that this corrosion is probably not an issue. The NGK site also states how important the torque spec is. This is part of the reason I have service manuals for everything. I always use a torque wrench for anything there is a spec listed for.....my buddies think I am crazy sometimes. I will still probably apply a very light coat of anti-seize to my plugs just because I wish to do so. I always apply the product to the upper 2/3 or so of the threads and only use a light coat so I have little concern with this getting into the engine. Everyone has their own preferences.

 

[pede58]

never seize is a good product and if you apply it right won't get into the engine, but with that said I'm in agreement with the rest and not use it here. I went to a Loctite class some time ago and it makes a far better never seize in most application, this is not one. Pipe on a torque wrench, really guy's? you need to bone up and spend some big bucks like I did for a 5ft long 600lb'er, funny thing is I have bolts even with that it takes a 4-1 multiplier to get the 2500lb required torque.

 

[POS POLARIS]

Always put anti sieze on spark plug threads. on any engine. generally always as a rule put antisieze on any bolts that go into an aluminum housing.

I just pulled plugs on a 700 last week that were about 500 hours old. they pulled out hard. They had no antizieze on them.

You wont get any in the engine if you don't glob it on there wipe some on the threads and install the plug. you will thank yourself later.

 

[commanderjjones]

I've never used anit-seize on spark plugs, but it does seem like a good idea.

I agree with Adam. If you don't use an excessive amount, it should never reach the combustion chamber to cause any problems.

 

[rowe doo]

Ive never put anti-seize on any plug and we have some sled's 50 years old one of em is a plug eater.

 

[gunguy]

I put it on them, it makes it alot easier to remove them the next time. You don't have to put a ton on there...
