broken cylinder head bolt
installed the head on my 04 civic used new head bolts snugged them all up in sequence as per manual but final torque the number one bolt broke off in the block torque stated 168 ft. pounds the other nine are fine looking for suggestions if anyone has encountered this I'm not real keen on drilling it out thanks
If you think a good mechanic is expensive, try hiring a bad one

WHOA! That spec is waaaay wrong. (and I'd like to know how you came up with that number)
No wonder it broke...the rest of them should have broken along with the first one.

Um.. Yeah.. 14 ft-lbs for the first round.. 36 for the second, 49 for the final round.. You applied >3x the required torque to those head studs.

Surprised you didn't strip block threads over-torquing that much. Back all the other ones out to correct final torque spec or they will rip threads when the engine heats up. Refer to this and manual for torque specs and sequence: https://www.justanswer.com/honda/294...l-non-cyl.html
