I keep breaking rocker arm bolts, help please!

Thanks everyone! As soon as I drill out this last bolt I will torque them down to 17ft/lbs w/o oil.

That sounds like a good plan to me.


Yes. I do think that most of the problem is too much torque, I didn't check the torque spec before my first post, but the lubrication on the bolts can get you in trouble also.

Only use it if the bolt manufacturer specifies it and the torque to use with it. I've seen many times where people put oil/lube on a bolt and it throws off the torque spec/requirements.
