i just checked the plugs out on my car and there is something funny about them. they are ngk's and have been on the car for about 5000 miles. they seem to have a nice tan color but there is also a light green color on the plugs? what can cause the green color? it couldn't be antifreeze could it? every plug has this green color so i know its not just on one cylinder. any suggestions???

if they are copper plugs, copper rusts green like that statue chick in ny.
check the last page of your haynes manual, it has pics of all kinds of worn plugs
