You are talking about the threads on the top of the spark plug right?The little cap might be stripped or just not on tight enough.If it is stripped then I would just buy new spark plugs and be done with it for such a small price to repair.Just mae sure that the small threaded end does not stay in the spark plug boot ok?

When you replace sparkplugs you remove the screw on ends.
Some aftermarket wires use the screw on part.
took the words right out of my mouth. The plugfs are fine, they're supposed to be that way.
