Brokoen bolt on engine mount

[ebv8]

my old AU did this every few months
i never used high tensile bolts just in case they snapped and i could not drill them out and use easy outs on them
i think the issue lied in the flushness of the engine mount to block face, even after torquing them up there was still flex in the plate and snapped the bolt after some time and lots off hard take offs

You are correct about the cause. A former member also broke many bolts until he replaced the engine mount with one that mounted flush to the block. No more broken bolts
