50k spark plugs

Just changed the spark plugs. I have 50k on them and 6 years. They looked fine to me. The junk on the thread is anti seize I think I put too much last time.

 

They look ok, but what is the gap??

 

Yeah that's probably too much antiseize. If you're insistent on using it, invest in some copper high temp instead of the silver stuff. Only use a tiny dab, don't need to fully coat them like the Silver Surfer.

And I second what is above, what's the gap?

 

you THINK you applied too much antiseize?! It looks like you rolled the threads in the dirt before taking a pic lol

 

The gaps were about 0.042-3

 

If you decide to use anti-seize, just put a small "hint" amount of it on an old toothbrush and sparingly brush it onto the threads. It should just barely cover/coat the metal. The plated threads on the Denso and NGK plugs also helps a lot. If you apply too much you can wipe the threads with a clean rag to remove the excess from the threads and the toothbrush.

 

Never use anti seize.
A few drops of oil and send it.

 

That's not horrible. I believe the gap should be between 43 and 45..

 

Even that would be an issue since oil on threads causes incorrect torque wrench readings (you end up with more torque than you have the wrench set to). My understanding is the NGK/Denso threads are designed to be used dry.

 

But they didn't seize, did they.

so as far as you (and I) can tell, you used enough to ensure you could get the plugs out.

I'm due to replace mine, too. i think i used the exact amount necessary for removal. we shall see.

 

I don’t use anti-seize, based on Denso advising against using it.

 

I'm a Tacoma newbie and a nobody but thought I would share and risk a roast. Also wanted to get a first post in!
2011 Dblcab, 4.0 V6, 120k miles.
Last week decided to change plugs as a matter of course.
Every one of them were scary tight all the way out. Had to spray Wd40 to get them to turn even slightly comfortably.
Finally got them all out without damage.
I did apply a small dab of copper anti-seize on new plugs threads.
I just couldn't put them back in dry. I know mfg instructions say different.
Just saying.

gap and go

I replaced mine after 200k + miles

Mine felt tight for few turns. The anti seize I used became like rubbery material. I put slight dap and installed the new ones. Since it’s not a bad job I might take them out again l, clean them and put a little of copper anti seize.
I did not check the gap on the new ones. Should I? They are oem from Toyota. I checked visually and there is no sign of damage on the tops.

 

always check the gap!

Mine had two that were too wide

 

Not only that, but most lubricating oils are probably going to at least partly break down into carbon, varnish, etc. due to the extended high operating temperatures just above the combustion chamber.

 

Not an issue and I find loose plugs from people using a good torque wrench because they can’t feel
The crush washer.
Never have I used a torque wrench on plugs.
Neither here or there but people using anti seize made plenty of house payments for me.

 

Go easy, it’s their first time

 

I’m being very easy…..LOL
