Question re: spark plug anti-seize
Did a spark plug change last week using some aluminum-containing anti-seize on the threads. Today I read the only copper anti-seize should be used. Some even recommend no anti-seize because it leads to over-torquing.
My question is whether it's worth the hassle of taking out the plugs to clean off the aluminum anti-seize and replace with copper stuff or nothing at all. Has anyone used the aluminum stuff and had no problems with the plugs fusing to the aluminum head a year later? I hate to go through the process all over again. |
you might want to...Al melts at a lower temp than Copper.

You'll be fine, as long as you put some sort of anti-seize then your okay. The only purpose of anti-seize is for aluminum heads so your good, no worries. :cool: |
My past 3 cars have all had aluminum heads and I have always used the standard silver anti-seize and have never had fusing issues.

Thanks! I feel better now.
