Are you using grade 8 bolts. I had that happen with a small block chevy years ago. Someone stole my alternator. When I replaced it I only used a grade 5 bolt. It sheared off in two days. I replaced it with a grade 8 and never had another problem. As far as what can come off under the hood, that depends on your local emission regulations.
