Loose sparkplugs -- What causes that???
Last weekend, the rear Leading plug was "loose".
This weekend, the front trailing plug was loose enough to turn with your fingers. Plugs were tight and anti-seazed just 2 weeks ago.
Searched but only found one reference to loose plugs with no resolution.
Thanks for any insight.

The other thing that occurred to me is that if the threads are completely glopped (is that a word?) with anti-seize it may be preventing you from properly torquing them down.

Also, god forbid you cross threaded the plugs, the plug can never seat properly thus never being "tight". I know you guys know from experience if you don't start the thread properly and just keep going it will spin on you then you're screwed lol.
Hopefully that didn't happen to you.

I also recommend only swapping plugs when the engine is cold. The housings expand when hot.
It's ironic you post this, because I have a close friend who was having this problem on his supercharged Mustang. One of his plugs kept backing out causing a ticking noise and underpower. We simply put a little more torque on them when tightening them down. Problem ceased.
