Broken stud bolt (valve cover bolt)

[crappycoco]

Done it, i did end up using some loctite on all of them, just to be sure and some of them were really loose when screwed in half way (which is where they needed to be).

Buttoned it up, fired up the engine. Works. For now =)
Thanks!

I just snapped the rearmost (bottom) one as well- and I was SO careful to actually torque in sequence to 15 n-m. So...even done "correctly", they can snap! Arghhh!
