yeah, though again its never been an issue i'm confident in assuming most folks don't use a tq. wrench on the cap, but maybe i'm way off base on that? hand tight and and a quarter turn with the tool historically has got it done. im going to use a tq. wrench this time just so I know its not over or under torqued! if the trifecta of new o ring, new cap and correct tq. spec doesn't do it ill have to explore my options.
