Well, generically speaking it's a "gasket," but technically it's an o-ring and you can inexpensively replace it separately. It's by design not a matter of tighten tighter, as you just turn the cap until it hits the stop..

While you're at it, replace the o-ring on the dipstick, too ... 'cause it's the same vacuum leak.
