well sounds like the thread snapped inside so cant do up tight anymore, take the cover off and inspect the damage, you may be able to recover and be very careful bolting it back up, or you will have to work out a way to tap and thread a hole for the stud.
Just my thoughts
I did put something here, but it vanshied, I think
hah, I did the same thing. By head bolt I assume you mean rocker cover bolt? I don't know what you'd be doing playing with the head bolts?
That snap was most likely the rocker pedestal breaking into pieces. The solution; a new one (you can seperate it from the rocker gear, just make sure it's identical). That or leave it, I drove around for months with mine broken and the bolt was holding just fine.
And get some EF/EL rocker cover bolts. You can't over tighten them, I guess they fit the ED rocker cover.
Ive had the "CracK" noise many times when tightening the rocker covers, each time it happens it scares the crap out of me as i think ive broken something, you'll probrably find its the rocker cover (or washers) grabbing on the thread on the studs. then again you could have broken something!!

it shouldnt make it leak from the side even though it made that crack sound, if anything the rocker cover may be warped causing it to not seal properly. to try and fix it pull it off again see if any of the rocker post are cracked, if not put it back on but run a bead of three bond underneath the gasket to try and take up any gaps. when i changed mine i got no leaks and only put some of that stuff around the half moons. also if the rockercover is cracked, and it is common on EA-ED then just replace it.
