Just my .02, but regardless of some articles I've read thru the years, I'd NEVER again use antiseize on my sparkplugs. If the OEMs use antiseize, it is only because they know people tend to leave plugs in for 10 years/100,000 miles. I have my plugs out every 2 or 3 years, so I wouldn't use, or need it again. Also agree with @mmartinez that grease on the tap will be superior to oil at holding any small metallic particles....

Yeah, that was the conventional wisdom with old champion plugs and cast iron heads. Spark plugs for LS engines are designed to go in dry. The plating on the spark plug threads acts as a release agent for removal. Antisieze does nothing except act as a lubricant, and alter the torque value.

This is the perfect example of why you must always start the spark plugs (as well as bolts, studs, nuts, lug nuts...) first by hand, so you can feel if there is any binding as well as to know for sure that the threads have been engaged properly. The person at that shop most probably was in a rush (or was inexperienced) and was using some type of a power tool.

To close the loop, I was able to successfully use the back tap tool and the threads look and work great. New plug is in and the misfire is gone! Thanks for all of the help and support!
