Anti-seize on spark plug threads is one of those things where less is more. If you put too much, it can melt and run into the combustion chamber, possibly shorting out the plug. So be sure to use it very sparingly.

 

What do you mean "good for 100k miles?" What plugs are you using?

Yes to anti-sieze and if you have it, the dielectric grease.

 

95% of the time my torque wrench is my right arm. The one time I used one and I wasn't going to it snapped a bolt off on my rear diff cover. Also some spark plugs come with instructions on how to tighten them without a wrench and also they will say what the specs are with or without anti-seize. Both are cheap insurance you can get in a little packet at the counter of any auto parts store or Wal-mart so if you can get it I would say just do it. I recently used a thin layer of vaseline on my battery terminals that corroded all the time and it's been a few months now and they still look great so IDK if that could be substituted here?

 

Improperly using a torque wrench is worse than not using one at all. At least, that's been my experience.

 

Ooops, just looked it up. Found it's 60K miles. Perhaps my truck will last that long.

Good thing my wife wanted new wipers, she went and got both the anti-seize and dielectric grease.

Thanks for all the input, y'all! I'll be posting a pic in a previous thread when I asked about gap importance... you wouldn't believe they were all huge; apparently due to wear! stay tuned....

 

It was a high quality torque wrench set by a certified mechanic right before I used it...I know certain things are important but I haven't had any problems with most things.

 

60K? Mine says replace at 30K from what I recall. I'll check in the morning.

 

Wow, I've been jumping between Chevy and Dodge too much. While I still had mine listed in my spreadsheet at 60K, the schedule clearly states every 30K. The Trailblazer are rated for 100K.

Sorry folks!

 

I know I'd never make 60k with my plugs. By 30k they're pretty much gone.

Thanks for checking Robba.
