[Vwdiesel] OT Somewhat--diesel tractor

[Dave Cook]

Hmm, my understanding of how dielectric grease works is that while it isn't a conductor, if you put a little bit on the plug, it will be pushed/scraped away from the actual connection point, and then the grease will seal the connection from water/corrosion.  I could see it being a problem if the connection wasn't secure.
