So I did a tune up, changed leaky valve cover, and while reading the torque spec's in the manual, it stated 80 ft. lbs, which seemed a bit much to me (not realizing it should of been inch pounds, which converts to 6 to 7 ft. lbs) So, needless to say I snapped 1 bolt (rookie move, at least it was only the one).
Can't understand why the manual would say ft. lbs, but at least I figured it out.
Sooooo, how can I remove the broken bolt? Also, one of the bolts doesn't seem to want to tighten up. It sits right, just wont tighten up. Any suggestions?
This is one where someone would have to see the situation to evaluate what needs to be done
If the broken bolt is sticking out then would try to grab it with vise grips
But, I am thinking it snapped close to the top of the head or even below the opening for the bolt
They don't usually snap off flat.
Would try using a punch .. pin
Try to make a dimple so the drill bit doesn't run around.
Then drill the bolt out using lots of cooling water or oil
Using bigger and bigger drill bits until you get close to the size of the bolt hole.
Then use a square or easy out to take out the rest
There are youtube videos on how to do this.
