I just finished my first tune up and every thing went very well and the truck runs great..

I have a question, however, about the spark plug tubes. When I took the number 3 plug out, the whole inside of the tube had a fine white crust on the inside. the other tubes were clean.

I checked all the plugs and they all appear normal except for the crud in this one tube.

Does anyone know what may have caused this?

Thanks.

Have no idea, though you may have had a bad wire that was arching once in a while which could oxidize the tube. If you haven't yet(i.e., if you're tune up didn't include wires), then call Dan and get a replacment wire set.
