someone either stripped them putting the plug in, or didn't put them screw them in all the way and it didn't have enough threads holding the plug down.


i don't have my PAIR valve anymore, so i have a little bit more room. but what i do is a use 5in extension on my plug socket and get them started by hand. by the time i usually have to put a rachet wrench on the extension - i get less than a half turn. just enough to snug the plug up.
